# Business Statistics Assistance

**Question description**

One I open the exam there is only 75 minutes for the exam. I believe there are 25 questions and I am honestly uncertain of how many I would need help with. Let's plan on 10 but it could be higher. Regarding price I do not know what to offer you o let's start with 15.00 and I will not accept the order, etc. until we complete the assignment so we can adjust the price accordingly. If that is not acceptable then please tell me how you want to handle it. You can accept and I can accept and at the end try to make an adjustment or put a tip that will adjust it to the final price we agree on.

If you need to view more examples let me know and I can either copy and paste them here or let you sign into the actual course to look at the 2 chapters completed. Unfortunately, there is a chapter included in the exam that I had not had homework in or have any idea what to expect.

This is a sample of one of the chapter questions

*[The following information applies to the questions displayed below.]*

A sample of 45 observations is selected from a normal population. The sample mean is 49, and the population standard deviation is 5. Conduct the following test of hypothesis using the 0.10 significance level. |

H_{0}: μ = 51 |

H_{1}: μ ≠ 51 |

a. | Is this a one- or two-tailed test? |

*Explanation:*

a. |

This test is two-tailed because the alternate hypothesis does not indicate a direction. |

b. | What is the decision rule? |

Reject *H*_{0} if z < -1.645 or z > 1.645

*Explanation:*

b. |

Since
this is a two-tailed test, half of the significance level 0.10, or
0.050 is placed in each tail. That means 0.4500 is the area between 0
and the critical value. Locate 0.4500 in the body of the standard normal
table. Then read the critical value from the row and column
corresponding to 0.4500. It is 1.645. The decision rule is: Reject |

c. | What is the value of the test statistic? |

Value of the test statistic | -2.68 |

d. | What is your decision regarding H_{0}? |

*Explanation:*

**d.**You reject *H*_{o }because -2.68 < -1.645.
