Answer #1

The hypothesis being tested is:

H_{0}: µ_{1} = µ_{2}

H_{1}: µ_{1} ≠ µ_{2}

Group 1 (Home) | Group 2 (OnSide Work) | |

120.60 | 99.60 | mean |

19.31 | 11.06 | std. dev. |

5 | 5 | n |

8 | df | |

21.000 | difference (Group 1 (Home) - Group 2 (OnSide Work)) | |

247.550 | pooled variance | |

15.734 | pooled std. dev. | |

9.951 | standard error of difference | |

0 | hypothesized difference | |

2.110 | t | |

.0678 | p-value (two-tailed) |

The test statistic is 2.110.

The df is 8.

The p-value is 0.0678.

Since the p-value (0.0678) is greater than the significance level (0.05), we fail to reject the null hypothesis.

Therefore, we cannot conclude that µ_{1} ≠
µ_{2}.

A random sample found that tourists in Chicago spent an average
of $2860 per week, with a standard deviation of $126. A separate
random sample found that tourists in Miami spent an average of
$2935 per week, with a standard deviation of $138.
The sample sizes are 89 for Chicago and 64 for Miami. Suppose
that you want to find out if there is any
difference between the average expenditures of all of the
tourists who visit the two cities....

1)Employers want to know which days of the week employees are
absent in a five-day work week. Most employers would like to
believe that employees are absent equally during the week. Suppose
a random sample of 71 managers were asked on which day of the week
they had the highest number of employee absences. The results were
distributed as in Table. For the population of employees, do the
days for the highest number of absences occur with equal
frequencies during...

1. The average work week for engineers in a start-up company
is believed to be about 60 hours. A newly hired engineer hopes that
it’s shorter. She asks 10 engineering friends in start-ups for the
lengths of their average work weeks. Based on the results that
follow, should she count on the
average work week to be shorter than 60 hours?
Data (length of average work week): 70; 45; 55; 60; 65;...
