Test the hypothesis with a significance level (alpha) of .05 that the climate has changed since industrialization. Suppose that the mean temperature throughout history is 52 degrees. During the last 30 years, the mean temperature has been 53 degrees and suppose the population standard deviation is 2 degrees. What can we conclude? Then construct a 95 percent confidence interval for the population mean.
Solutions
Expert Solution
Note : We have used 53 as sample mean because we have concluded from test that our null hypothesis is rejected.

Test the hypothesis (at the .05 level
of significance) that individuals who were bullied are more likely
to bully others. Test the hypothesis (at the .05 level of
significance) that individuals who were bullied committed more
bullying than those who were not bullied

For a two-tailed hypothesis test at the significance level
alpha, the null hypothesis H0: μ = μ0 will be rejected in favor of
the alternative hypothesis Ha: μ≠ μ0 if and only if μ0 lies outside
the (1 - α) level confidence interval for μ. Illustrate the
preceding relationship by obtaining the appropriate one-mean
z-interval for the data below.

In a hypothesis test, the significance level α (alpha)
represents the threshold for how unlikely sample data has to be,
assuming the null hypothesis, in order for us to reject the null
hypothesis. Often alpha is taken to be 0.05, or 1/20, which means
that even if the null hypothesis is true, there is a 1/20
chance that we will reject it because our sample data happens to
have a P-value less than 0.05.

A hypothesis test with a 5% level of significance is designed to
test the claim that the mean weight of a new breed of chickens is
greater than 6.00 pounds. A sample of 81 chickens is obtained and
their mean weight is 6.20 pounds with a sample standard deviation
of 0.50 pounds. No information is available concerning the standard
deviation of the whole population of the new breed. What is the
critical value (from Table A-3) and the test statistic...
