Based on a random sample of 25 units of product X, the average weight is 102 lbs., and the sample standard deviation is 10 lbs. We would like to decide if there is enough evidence to establish that the average weight for the population of product X is greater than 100 lbs. Assume the population is normally distributed. What is the critical value (given in terms of the value of the test statistic) at α = .05?

Based on a random sample of 25 units of product X, the average weight is 102 lbs., and the sample standard deviation is 10 lbs. We would like to decide if there is enough evidence to establish that the average weight for the population of product X is greater than 100 lbs. Assume the population is normally distributed. What is the sample value of the test statistic? A. -1.00 B. 3.16 C. 1.00 D. 2.00 AACSB: Analytic Bloom's: Application Difficulty: Medium Topic: Hypothesis testing 1-777 Chapter 01 - An Introduction to Business Statistics 63. Based on a random sample of 25 units of product X, the average weight is 102 lbs., and the sample standard deviation is 10 lbs. We would like to decide if there is enough evidence to establish that the average weight for the population of product X is greater than 100 lbs. Assume the population is normally distributed. What is the p-value for this test? A. 8413 B. 0228 C. 3174 D. 1587 Greater than hypothesis with a t = 1.00; 1 - .8413 = .1587 AACSB: Analytic Bloom's: Application Difficulty: Medium Topic: Hypothesis testing 64. A recent study conducted by the state government attempts to determine whether the voting public supports further increase in cigarette taxes. The opinion poll recently sampled 1500 voting age citizens. 1020 of the sampled citizens were in favor of an increase in cigarette taxes. The state government would like to decide if there is enough evidence to establish whether the proportion of citizens supporting an increase in cigarette taxes is significantly greater than .66. Which of the following does not represent a null hypothesis? A. p < .66 B. p > .66 C. p = .66 D. p ≤ .66 AACSB: Reflective Thinking Bloom's: Comprehension Difficulty: Easy Topic: Hypothesis testing 1-778 Chapter 01 - An Introduction to Business Statistics 65. A recent study conducted by the state government attempts to determine whether the voting public supports further increase in cigarette taxes. The opinion poll recently sampled 1500 voting age citizens. 1020 of the sampled citizens were in favor of an increase in cigarette taxes. The state government would like to decide if there is enough evidence to establish whether the proportion of citizens supporting an increase in cigarette taxes is significantly greater than .66. The alternative hypothesis is: A. p < .66 B. p > .66 C. p = .66 D. p ≤ .66 AACSB: Reflective Thinking Bloom's: Comprehension Difficulty: Easy Topic: Hypothesis testing 66.
