If original program is x hours long we have the equation-
x - 0.17x = 1.5
0.83x = 1.5
x = 1.5 / 0.83 = 1.81 hours long ( about 1 hour 49 minutes) Answer
Answer:x=42
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable

Answer:
The right option is:
b. There is enough evidence to conclude the mean difference in pulse rates before and after the 5 minute waiting period is different from 0.
Step-by-step explanation:
The null hypothesis is the opposite to the claim that the researchers are trying to prove. In this case, it will state that there is no difference in the mean pulse rates or, in other words, that the mean difference in pulse rates before and after the 5 minute waiting period is 0 (μ=0).
The claim of the researchers, that will be expressed in the alternative hypothesis, is that the mean difference in pulse rates before and after the 5 minute waiting period differs from 0 (μ≠0).
If the null hypothesis is rejected, is because the test shows that there is enough evidence to support the claim that the mean difference in pulse rates before and after the 5 minute waiting period differs from 0 (true alternative hypothesis).
Note: If the null hypothesis wasn't rejected, the conclusion would have been that there is no evidence o support the claim that the mean difference in pulse rates before and after the 5 minute waiting period differs from 0.
The right option is:
b. There is enough evidence to conclude the mean difference in pulse rates before and after the 5 minute waiting period is different from 0.
