Construct a 90% confidence interval for the  population mean, μ{“version”:”1.1″,”math”:”\mu “}

There is insufficient evidence at the 10% level of significance to reject the district’s claim that the mean hourly sales are at least $750.

The correct decision for this test is to 

State the p-value or sketch the sampling distribution and the rejection region given by the critical value. 

Construct a 90% confidence interval for the  population mean, μ{“version”:”1.1″,”math”:”\mu “}

There is enough evidence, at the 5% level of significance, to support the school board’s claim that a majority of the community wants to change the school’s name.

The null and alternative hypothesis for this test are: H0:μ≥750Ha:μ

State your null and alternative hypotheses as “H_0: answer” and “H_a: answer”

Interpret the decision in the context of the claim.

Either state the p-value or sketch the sampling distribution and determine the critical value(s) on your scratch paper. Type 1 here if you sketch the samp. distr.
