Q 20 Suppose you want to determine at the 5% significance level if the proportion of adults who use different streaming services is equal. Let p1 = the proportion of adults who use Netflix, pp = proportion who use Amazon Prime, p3 = proportion who use Hulu, and pa = proportion who don't use a streaming service. To test, you take a random sample of 200 adults and find that 38% use Netflix, 23% use Amazon Prime, 12% use Hulu, and 27% don't use a streaming service. What is the correct null and alternative hypothesis? Select one: O a. Ho:p1= 38. p2 -.23. p3 =12, 04 =.27, Ha : At least two proportions are equal D. Ha : p1 =p2 - p3 -p4 =1/4. Ha : At least one proportion is different. O c. Ho:p1 -.38. p2 -.23. p3 =12, p4 =.27, Ha : At least one proportion is different. O d. He : p1=p2 = p3 =p4 =1/4. Ha: At least two proportions are equal. Oce. Ho:p1=76. p2 =46, 53 =24. p4 =54. Ha : At least one proportion is different
