Suppose a manager used this dataset to test the null hypothesis that the population mean payment error is less than or equal $15 versus the alternative hypothesis that the population mean is greater than 15$. What is the critical value of the t test at a level of significance of 0.01? (answer to 3 decimal places) $17 $25 $14 $-10 $20 $40 $35 $30 $28 $22 $15 $16

A random sample of size 15 is selected from a normal population. The population standard deviation is unknown. Assume the null hypothesis indicates a two-tailed test and the researcher decided to use the 0.05 significance level. For what values of t will the null hypothesis not be rejected? To the left of -1.282 or to the right of 1.282 To the left of -1.345 or to the right of 1.345 Between -2.145 and 2.145 To the left of -1.645 or to the right of 1.645

A hypothesis will be used to test that a population mean equals 5 against the alternative that the population mean is less than 5 with unknown variance. What is the critical value for the test statistic $T_{0}$ for the following significance levels? (a) $\alpha=0.01$ and $n=20$ (b) $\alpha=0.05$ and $n=12$ (c) $\alpha=0.10$ and $n=15$
