Question

You may need to use the appropriate appendix table or technology to answer this question.

The following results come from two independent random samples taken of two populations.

Sample 1 | Sample 2 |
---|---|

n
_{1} = 60 |
n
_{2} = 35 |

x
_{1} = 13.6 |
x
_{2} = 11.6 |

σ
_{1} = 2.2 |
σ
_{2} = 3 |

(a)

What is the point estimate of the difference between the two population means? (Use

x_{1} − x_{2}.)

(b)

Provide a 90% confidence interval for the difference between the two population means. (Use

x_{1} − x_{2}.

Round your answers to two decimal places.)to

(c)

Provide a 95% confidence interval for the difference between the two population means. (Use

x_{1} − x_{2}.

Round your answers to two decimal places.)to
