1. You collect a random sample of 100 children and compute X= 47.5 inches, the average height in inches. The sample standard deviation (s) equals 6 inches. You conduct a two-sided hypothesis test where Ho: u = 46 inches. Which of the following statements are true: I. You reject the null hypothesis when a = 0.05 I. You reject the null hypothesis when a = 0.01 Ill. The test statistic (Z) equals Z = +2.5 (ANSWER CHOICES) O None of the Above O land Ill only O Ill only O ll only O l only 2. You collect a random sample of 100 children and compute X = 47.5 inches, the average height in inches The sample standard deviation (s) equals 6 inches. Conduct a two-sided hypothesis test where Ho: M = 46 inches. Compute the p-value. 3. You conduct a poll of FIU students in order to determine the percentage of students (p) who agree with the statement "Hot-dogs are one of my favorite foods". In your poll, you find that 80 out of 100 students agree. You conduct a two-sided hypothesis test where Ho: p = 0.7. where p is the proportion of students whose favorite food is hot dogs. Which of the following statements are true: I. You reject the null hypothesis when a = 0.05 II. You reject the null hypothesis when a = 0.01 III. The test statistic (Z) equals Z = +1.5 (ANSWER CHOICES) O Ill only O Il only O I only O None of the Above O l and Il only 4. You conduct a poll of FIU students in order to determine the percentage of students (p) who agree with the statement "Hot-dogs are one of my favorite foods". In your poll, you find that 80 out of 100 students agree. You conduct a two-sided hypothesis test where Ho: p = 0.7. where p is the proportion of students whose favorite food is hot dogs. Compute the p-value. 5. You collect data on N = 25 student weights and find that the average student weight X in your sample is 135 pounds. The sample standard deviation (s) is 5 pounds. You conduct a two-sided hypothesis test where Ho: M = 134 pounds. Which of the following statements are true: I. You reject the null hypothesis when a = 0.05 II. You reject the null hypothesis when a = 0.01 Ill. The test statistic (T) equals T=+1 (ANSWER CHOICES) O l only O All of the Above O None of the Above O l and Ill only O lll only
