Answer:

S=45m+15

Step-by-step explanation:

we have

E------>the number of sit-ups

m---->  the time in minutes

S----> the number of sit-ups after drinking the sports drink

E=15m+5 ----> equation A

S=3E ----> equation B

substitute the equation A in the equation B

S=3(15m+5)

S=45m+15

A statistician wants to determine if there is a difference in the fuel efficiency of cars between model years. To do this, he se
Elodia [21]

Answer:

P-value = 0.00028

Step-by-step explanation:

The statician performs an hypothesis test for the mean difference.

As the alternative hypothesis is<em> Ha: μd ≠ 0</em>, we know that it is a two-tailed test.

The test statistic is t=6.163.

For a two-tailed test and 8 degrees of freedom, this corresponds to a P-value of:

\text{P-value}=2\cdot P(t>6.163)=0.00028

This P-value is smaller enough to reject the null hypothesis at almost any significance level.
