Andrew, a fitness coach for a large oil company, would like to test if his exercise program has increased muscle mass in his cli
vodka [1.7K]

Answer:

Reject H_0

The test statistic is in the rejection region

Step-by-step explanation:

Since we want to test if the mean predicted by the coach is greater than the mean of the null hypothesis \bf H_0, this is a right-tailed test. It means that, in order to reject \bf H_0, the test statistic must fall to the right (greater than) of the critical value \bf z_0

Given that 2.56 > 1.65 then we reject \bf H_0

<em>The test statistic is in the rejection region (greater than 1.65) </em>

Roxy is multiplying 1/8 by 4/3
Vera_Pavlovna [14]

Answer:

1/6

Step-by-step explanation:

Make the denominators the same by finding the lcm(least common denominator). The least common demominator would be 24. So multiply both numbers in 1/8 by 3. This would eaqual 3/24. Multiply both numbersin 4/3 by 8. This would equal \frac{3}{24}  *  \frac{32}{24} = \frac{96}{576}. Simplify 96/576 by dividing both numbers by 96.

<u>96</u> ÷ 96 = <u>  1  </u>                                                                                                              576 ÷ 96 = 6 and that becomes 1/6.

Queen = 4/52 reduces to 1/13

1/13 *1/13 = 1/169

 so none of the above
