1. Pivot joint 

2. Fibrous joint 

3. Saddle joint 

4. Ball and socket joint

An experiment in which the outcome of that experiment cannot be predictable is called random experiment.

The number of positive allocation in a basic feasible solution (B.F.S) is less than (m + n – 1), then the solution is called to be degenerate.

Statistical constants of the population such as Mean – μ, S.D – σ are called ‘Parameters’.

Lead time is the time gap between placing order and arrival of goods at the inventory.

Variance = 2n = 10; Mean = n; 

∴ n = \(\frac{10}{2}\) = 5.

Mean > Variance i.e., np > npq.

Source and foot note are written just below the table. The data obtained from publications, offices, journals can be mentioned under source and to explain omissions, abbreviations, remarks about numerical entries of the table can be given under the footnote.

The following are the important functions of statistics: 

(a) It simplifies and condenses the size of the data. 

(b) It facilitates composition. 

(c) It enriches our knowledge and widens our experience. 

(d) It helps in formulating policies. 

(e) It helps in business forecasting. 

(f) It presents the facts in a definite form.

Here mode(Z) = 4. Repeated more number of times.

Correlation is said to exists between two variables, if they vary directly or indirectly together.

(i) 3-Phenylpropanoic acid
(ii) 3-Methylbut-2-enoic acid
(iii) 2-Methylcyclopentanecarboxylic acid
(iv)2,4,6-Trinitrobenzoic acid

Croxton and Cowden defines ‘statistics is the science of collection, presentation, analysis and interpolation of numerical data.

Bernoulli distribution has parameter – p or mean = p or variance = p (1 – p).

(a) Multiple bar diagram 

(b) percentage bar diagram.

Ranks are given to students according to their marks scored in examination.

It is the ratio of frequency of the value of a variable to the total frequency.

If the data is classified on the basis of qualitative characteristics or attributes is called qualitative classification.

A set of real value X = (x₁,x₂,……….x_n), which satisfies the constraints A X(≤ = ≥)b, is called a solution.

The probabilty that the confidence interval contains the parameter is called confidence coefficient (1 – α).

The set of all those values of the test statistic, which leads to the rejection of the bull hypothesis, is called critical region (w).

A small amount of variation for which no specific cause can be observed in the quality of the product, this variation is called as ‘chance causes’.

Pivot is the type of movable joint present between the atlas and axis.

1. Ball and socket joint (between humerus and pectoral girdle) 

2. Hinge joint – knee joint

1. Ball and socket joint 

2. Shoulder joints and Hip joints 

3. In ball and socket joint, one of the bones forms a ball like head while the other forms a cup like socket into which head fits in. It allows the free movement of the bone with the ball like head.

1 degrees of freedom.

In a 2 × 2 contingeven table N – is frequency of zero order, is 

obtained as N = (A) + (B) 

∴ N = 130 + 120 = 250.

Following are some important points/rules to be considered while framing a questionnaire. 

1. Questions should be simple and easy to understand and get spontaneous answers. 

2. Questions should not confuse the reader and they should give only one meaning. 

3. The number of questions should be kept to a minimum. 

4. Questions should be such that people with little intelligence and educated ones can both answer without much difficults. 

5. The questions should be arranged in a logical order. 

1. Non-striated muscle (smooth muscle) 

2. Smooth muscles are involuntary muscles located in the inner visceral organs like alimentary canal, reproductive tract etc. So they help the transportation of food through digestive tract and gamete through the genital tract.

Muscles of the hand are skeletal muscles and they are voluntary muscle. Muscles of the heart are cardiac muscles and they are involuntary muscles.

1. When temperature increases muscle contraction increases, but when temperature decreases the extend of muscle contraction decreases, but the time remain in the contracted state increases, 

2. Actin and myosin

1. The lower limit of the first class is either’O’or a multiple of 5. 

2. Exclusive classes should be formed for better continuity. 

The coefficient of correlation is  

1. Independents of units of measurement  

2. Independent of orgin and scale.

1. Red muscle and white muscle. 

2. Red muscles contain large amount of mitochondria and myoglobin whereas the white muscles contain only less amount of mitochondria and myoglobin. 

3. Examples 

• Red muscles – Extensor muscles on the back. 
• White muscles – muscles of the eye ball

ATPase of the muscle is located in Myosin

This type of joint in called synovial joint or freely movable joint and allows considerable movement. 

eg: 

1. Ball and socket joint (between humerus and pectoral girdle) 

2. Hinge joint (knee joint)

1. Region 2 During Muscular contraction amount of Ca²⁺ released from ER is very high. 

2. Thick lament – Muscle protein – myosin Thin lament – Muscle protein – actin, troponin, tropomyosin.

3. Muscle contraction is regulated by a regulator protein troponin. Troponin mask the active site of actin molecule from myosin head, Action potential reaching a muscle cause the ER to release Ca²⁺ . 

This Ca²⁺ bind with the specific site of troponin. It causes a conformational change by which the active site of actin molecule is exposed and it results in cross bridge activity and muscle contraction.

1. Fibrous joints: They are immovable joints of the bones of skull whereas all others are freely movable joints. 

2. Femur: It is the thigh bone whereas all other are the bones of the forelimb
