Question
Transcribed Image Text:A random sample of 100 observations is selected from a binomial population with unknown probability of success, p. The computed value of p is equal to 0.73. Complete parts a through e.
Find the rejection region for the test. Choose the correct answer below.
O A. z< -2.575
OC. z< -2.33 or z>2.33
OE. z<-2.575 or z>2.575
Calculate the value of the test statistic.
z= (Round to two decimal places as needed.)
Make the appropriate conclusion. Choose the correct answer below.
b. Test Ho: p=0.63 against H₂: p>0.63. Use α = 0.10.
Find the rejection region for the test. Choose the correct answer below.
O A. Reject Ho. There is sufficient evidence at the α = 0.01 level of significance to conclude that the true proportion of the population is greater than 0.63.
O B. Do not reject Ho. There is insufficient evidence at the x = 0.01 level of significance to conclude that the true proportion of the population is greater than 0.63.
OC. Do not reject Ho. There is sufficient evidence at the α = 0.01 level of significance to conclude that the true proportion of the population is greater than 0.63.
OD. Reject Ho. There is insufficient evidence at the a= 0.01 level of significance to conclude that the true proportion of the population is greater than 0.63.
OA. z< -1.645
OC. z< -1.645 or z> 1.645
OE. z< -1.28 or z> 1.28
C
Calculate the value of the test statistic.
OB. z>2.33
OD. z>2.575
OF. z<-2.33
OB. z> 1.645
OD. z> 1.28
OF. z< -1.28
