Chloe works in the marketing department of the chain and is assigned to answer the owners' inquiry. She randomly selects 196 customers from various stores in the chain and finds that 114 use the loyalty card. What are the null and alternative hypotheses for this hypothesis test?

Select the correct answer below:

{H0:p=0.63Ha:p>0.63

{H0:p=0.63Ha:p<0.63

{H0:p≠0.63Ha:p=0.63

{H0:p=0.63Ha:p≠0.63

Answer 1

TOPIC:Identifying the correct null and alternative hypotheses.

Here, a sample size - 196. is a sample proportion = 16 ps Population proportion of using loyalty card. Let y claim. : The percentage of shoppers in their stores who use loyalty card, has changed from 631. in 2014. (ie. whether the proportion has changed from 0. 63), =) Hence, the connect wall and alter- native hypotheses are Ho : p = 0.63 against da : p +0+63 Ans),
