Question

3 In a sample of 1000 people in Karnataka, 540 are rice eaters and the rest are wheat eaters. Both rice and wheat eaters are equally popular in the state.
Calculate the value of the test statistic of single proportion?​

Answer 1

Answer:

460

Step-by-step explanation:

the people where eaters are rice and wheat. the eatern people is 540 and the population of Karnataka is 1000 so we decrease the total population - total no of eaters . so our answer is 460

Answer 2

Step-by-step explanation:

n = 1000

p = sample proportion of rice eaters

p= 540/1000

P = population proportion of rice eaters

P= 1/2 = 0.5

Q =1-P=1-0.5=0.5

Null hypothesis

Both rice and wheat eaters are equally popular in the state

H0 : P=0.5

Alternative hypothesis H1: P is not = 0.5

(two tailed test)

$z = \ p - P \div \sqrt{ \frac{p \times q}{n} }$

=2.53

The calculated value of z=2.53.
