A drapery store manager was interested in determining whether a new employee can install vertical blinds faster than an employee who has been with the company for two years.
The manager takes independent samples of 10 vertical blind installations of each of the two employees and computes the following information. 
a. State the appropriate null and alternative hypotheses to test whether the new employee installs vertical blinds faster, on the average, than the veteran employee.
______________
b. Calculate the pooled estimate of the common variance.
______________
c. Calculate the value of the test statistic.
______________
d. Set up the appropriate rejection region for the hypotheses in question 41 assuming
= 0.05.
______________
e. What is the appropriate conclusion?
The new employee ______________ install vertical blinds faster than the veteran employee.
Vertical Blinds
Window coverings consisting of vertical slats that can be adjusted to control light and visibility.
Null Hypothesis
A statistical hypothesis that assumes no significant difference or effect in a particular situation, serving as the default assumption to be tested against an alternative hypothesis.
Alternative Hypothesis
A statistical hypothesis that specifies a population parameter's value is different from the value stated in the null hypothesis.
- Comprehend and utilize hypothesis testing for determining population means.
- Compute and elucidate test statistics along with p-values.
- Implement hypothesis testing to evaluate the differences in means between two groups.
