1.	Out of 8000 graduates in a town, 800 are females and out of 1600 graduatesemployees. 120 are females. Use x2to determine if any discrimination is made in appointment on the basis of gender.
Answer» Answer: Explanation: Employment Unemployment Total Males 1480 5720 7200 Females 120 680 800 Total 1600 6400 8000 Let us TAKE the null hypothesis that no distinction is MADE in appointment on the basis of sex. Applying x² test E₁₁ = 7200 /8000 ₓ 1600 = 1440 The table of expected frequencies is given below: 1440 5760 7200 160 640 800 1600 6400 8000 Observed FREQ Expected freq ( Oi - Ei)² ( Oi - Ei)² /Ei 1480 1440 1600 1.111 120 160 1600 10.00 5720 5760 1600 0.278 680 640 1600 2.500 13.889 x² = 13.889

Answer:

Explanation:

Employment Unemployment Total

Males 1480 5720 7200

Females 120 680 800

Total 1600 6400 8000

Let us TAKE the null hypothesis that no distinction is MADE in appointment on the basis of sex.

Applying x² test

E₁₁ = 7200 /8000 ₓ 1600 = 1440

The table of expected frequencies is given below:

1440 5760 7200

160 640 800

1600 6400 8000

Observed FREQ Expected freq ( Oi - Ei)² ( Oi - Ei)² /Ei

1480 1440 1600 1.111

120 160 1600 10.00

5720 5760 1600 0.278

680 640 1600 2.500

13.889

x² = 13.889
