Question

1) Assume that a simple random sample has been selected from a normally distributed population and test the given claim. State the final conclusion that addresses the original claim and select three correct choices. Use a significance level of α=0.05 to test the claim that μ=32.6 The sample data consist of 15 scores for which x¯=41.6x and s=8. Use the traditional method of testing hypotheses.

A) There is enough evidence to reject the H0

B) There is enough evidence to support the Claim

C) H0:μ=32.6(claim)

H1:μ≠32.6H1:μ≠32.6

D) Not enough evidence to reject the Claim

E) Not enough evidence to reject the H0

F) There is enough evidence to reject the Claim

G) H0:μ≥32.6(claim)

H1:μ<32.6H1:μ<32.6

H) There is enough evidence to support the H0

I) None of these

2) Suppose we have 3 distinct people, 4 identical math books, and 5 identical history books. How many different (distinguishable) ways can ALL the books be distributed to the students?

A) 5!+3!+4!

B 5! / 3!.4!

C) 3!.4! / 5!

D) None of These

C) H0:μ=32.6(claim) H1:μ≠32.

F) There is enough evidence to reject the Claim

2)D) None of These

A simple random sample of 48 adults is obtained from a normally
distributed population, and each person's red blood cell count
(in cells per microliter) is measured. The sample mean is 5.19 and
the sample standard deviation is 0.53. Use a 0.01 significance
level and the given calculator display to test the claim that the
sample is from a population with a mean less than 5.4, which is a
value often used for the upper limit of the range of...
