We have a random sample of 36 data palrs where the sample mean of the differences is 1.18 and the sample standard devlation of the differences Is 3. Then the sample test statistic Is d = 1.18 Using these values, along with u = 0, we calculate the corresponding t value for the test statistic. 1.18 - 0 V V36 0.065

The test statistic of z=−2.97 is obtained when testing the claim that p=3/5.   a. Using a significance level of a=0.10, find the critical​ value(s).   b. Should we reject H 0or should we fail to reject H 0​?

The test statistic of z=−2.15 is obtained when testing the claim that p=4/7. a. Using a significance level of α=0.01​, find the critical​ value(s). b. Should we reject H0 or should we fail to reject H0​?

16% of all college students volunteer their time. Is the percentage of college students who are volunteers smaller for students receiving financial aid? Of the 313 randomly selected students who receive financial aid, 31 of them volunteered their time. What can be concluded at the αα = 0.10 level of significance? For this study, we should use Select an answer z-test for a population proportion t-test for a population mean  The null and alternative hypotheses would be:       H0:H0:  ? p μ  Select an answer < ≠ = >  (please enter a decimal)     H1:H1:  ? μ p  Select an answer > ≠ = <  (Please enter a decimal) The test statistic ? t z  = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is ? > ≤  αα Based on this, we should Select an answer reject accept fail to reject  the null hypothesis. Thus, the final conclusion is that ... The data suggest the population proportion is not significantly lower…

The test statistic of z= -1.90 is obtained when testing the claim that p<0.26. a. Using a significance level of a=0.01​, find the critical​ value(s). b. Should we reject Upper H 0 or should we fail to reject Upper H 0​?
