The government claims that the average age of Californians is 34 years Joe hypothesizes that the average age of the population of California is not equal to 34 years. He records a sample mean equal to 37 and states the hypothesis as μ = 34 vs μ ≠ 34.
What type of test should Joe do?
Homework Answers
Answer: Joe will do Two-tailed test
Ho: μ = 34
H1; μ ≠ 34.
Here Joe want to check whether the average age of the population of California is equal to or not 34 years.
Hence it is two tailed test.
if Population standard deviation (
) is given then
Joe will do Two
tailed Z test
if sample standard deviation (s) is given then Joe will do Two tailed t test

A sporting goods store believes the average age of its customers is 34 or less, but a competitor wants to challenge this. A random sample of 38 customers was surveyed, and the average customer age was found to be 37.5 years. Assume the standard deviation for customer age is 7.0 years. Using a = 0.05, complete parts a through d below a. Does the sample provide enough evidence to refute the age claim made by the sporting goods store? Determine...

An industrial and organizational psychologist hypothesizes that applied mathematicians, such as actuaries, are less extroverted than the general population. To test his hypothesis, he recruits applied mathematicians into a study (assume it is a simple random sample) and obtains 21 completed questionnaires measuring the Big Five dimensions of personality (neuroticism, extroversion, openness to experience, agreeableness, and conscientiousness). Personality dimensions measured by the instrument are normally distributed in the general population, and are reported as ?t‑scores, with a mean of 50...
