Ergonomic keyboards may increase typing speed. Ten administrative assistants were chosen to type on both standard and ergonomic keyboards. The resulting word-per-minute typing speeds are shown below. Complete parts a and b. Conduct a hypothesis test to determine if the ergonomic keyboards increase the average words per minute attained while typing. Use a p-value approach with a significance level of

0.01.

A.) Calculate T-Test

B.) Calculate P value.

Please show step-by-step or excel functions if easier. Thank you!
