Topic: Hypothesis testing 60. 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?
A. 1.645

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
