Answer #1

Here,

n = 111

x = 47

p0 = x/n = 47/111 = 0.423423423

np0(1-p0) = 111*0.423423423*(1-0.423423423) = 27.0990991 \approx 27.1 (Round answer to 1 decimal place)

np0(1-p0) = 27.1

Because np0(1-p0) = 27.1 > 10. the sample size is greater than 5% of the population size, and the sample

is given to be random, the requirements for testing the hypothesis are satisfied.

Summary :-

Because np0(1-p0) = 27.1 > 10. the sample size is greater than 5% of the population size, and the sample

is given to be random, the requirements for testing the hypothesis are satisfied.
