Question

Assume that a simple random sample has been selected from a normally distributed population. We want to test the claim that for the population of female college students at a particular university, the mean weight is given by μ=155lb. The sample data are summarized as follow: n=20, x=160lb, and s=18.5 lb. Use a significant level of α=0.5. a. Identify the relevant variable and parameter b. State null and alternative hypothesis c. Find the test statistic value d. Find and interpret the P-value and interpret the conclusion e. Is there a probability of making type I error (Yes or No).

Answer #1

Assume that a simple random sample has been selected from a
normally distributed population and test the given claim. Identify
the null and alternative hypotheses, test statistic, P-value, and
state the final conclusion that addresses the original claim. A
coin mint has a specification that a particular coin has a mean
weight of 2.5 g. A sample of 36 coins was collected. Those coins
have a mean weight of 2.49427 g and a standard deviation of 0.01141
g. Use a...

Assume that a simple random sample has been selected from a
normally distributed population and test the given claim.
Test
the given claim. Identify the null hypotheses, alternative
hypothesis, test statistic, P-value,
critical value(s), conclusion about the null hypothesis, and final
conclusion for the
original claim. Try both ways the P-valued method and traditional
method.

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.

indicated. Identify the null and alternative hypotheses, test
statistic, critical value(s) or P -value, and state the final
conclusion that addresses the original claim. A researcher wants to
