D Question According to a recent census, 14% of the people in the United States are of Hispanic origin. One county supervisor believes her county has a different proportion of Hispanic people than the nation as a whole (p 0.14). She looks at their most recent survey data, which was a random sample of 460 county residents, and found that 42 of those surveyed are of Hispanic origin. Test statistic Z is found to be -3.01. Use a = 0.01. What is (are) critical value(s)? 13.29 +2.576 1.645 3.09 2.33 1 pts 1.96 Question 5 In 1960, census results indicated that the age at which men in a certain region first married had a mean of 23.5 years. We want to find out if the mean age of first marriage has changed/differed from 23.5 years since then. The 40 men in our sample first married at an average age of 24.3 years, with a sample standard deviations of 5.3 years. Calculate the test statistic t. 0.955 0.145 1.171 1 pts 1.074 Question 6 1 pts In 1960, census results indicated that the age at which men in a certain region first married had a mean of 23.5 years. We want to find out if the mean age of first marriage has changed/differed from 23.5 years since then. We plan to test our hypothesis by selecting a random sample of 45 men who married for the first time last year. Assume a is unknown and level of significance of 0.10. Name the model. OZ-Test for one proportion Ot-Test for one mean with 44 degree of freedom. t-Test for one mean with 22.5 degree of freedom. Z-Test for one mean D Question 8 Ahmadi, Inc. has been manufacturing small automobiles that have averaged 50 miles per gallon of gasoline in highway driving. The company has developed a more efficient engine for its small cars and now advertises that its new small cars average more than 50 miles per gallon in highway driving. An independent testing service road-tested 64 of the new small automobiles. The sample showed an average of 51.5 miles per gallon. The population standard deviation is 4 miles per gallon. Ahmadi, Inc wants to conduct a hypothesis test to determine whether or not it is legitimate campaign that the new small cars average more than 50 miles per gallon in highway driving. Use [@] = 0.05 For the p-value approach, rejection rule is to reject Ho if p-value < 0.05 p-value < 1.645 1 pts Op-value <3 p-value > 3 p-value > 0.05 Question 9 Ahmadi, Inc. has been manufacturing small automobiles that have averaged 50 miles per gallon of gasoline in highway driving.

P(Z > 3)*2=0.0027 P(Z > 3)=0.00135 1 pts P(Z <3) 0.99865 P(Z <-3)=0,00135 - Question 12 1 pts A test of Ho: p = 0.7 vs. HA: p=0.7 rejects the null hypothesis. Later it is discovered that p = 0.85. What type of error, if any, has been made? Type I error occurred because the null hypothesis should not have been rejected. A Type Il error occurred because the null hypothesis should have been rejected. No error occurred because the null hypothesis was rightfully rejected.
