3w. Need help with parts a-e

For this series of questions, you will calculate confidence intervals and perform a one-sample t-test for the following data set:

17 , 15 , 16 , 16 , 15 , 13 , 17 , 19

 

a.What is the lower bound of the 95% confidence interval.

 b.What is the lower bound of the 99% confidence interval.

c.What is the critical t value for a one-sample two-tailed t-test for a significant difference?

d.What is the absolute value of the calculated t value for a one-sample two-tailed t-test?

e.What is the appropriate conclusion if the hypothesized population mean is 14?(photo attached)

The population mean appears to be significantly larger than 14 (p>0.05) The population mean appears to be significantly larger than 14 (0.04<p<0.05) The population mean appears to be significantly larger than 14 (0.02<p<0.04) The population mean appears to be significantly larger than 14 (0.01<p<0.02) The population mean appears to be significantly larger than 14 (0.001<p<0.01) The population mean appears to be significantly larger than 14 (p<0.001) The population mean does not appear to be significantly different from 14 (p>0.05) The population mean does not appear to be significantly different from 14 (0.04<p<0.05) The population mean does not appear to be significantly different from 14 (0.02<p<0.04) The population mean does not appear to be significantly different from 14 (0.01<p<0.02) The population mean does not appear to be significantly different from 14 (0.001<p<0.01) The population mean does not appear to be significantly different from 14 (p<0.001)
