Hatshy [7]

Answer:

The 99% confidence interval for the mean peak power after training is [299.4, 330.6]

$299.4\leq\mu\leq 330.6$

Step-by-step explanation:

We have to construct a 99% confidence interval for the mean.

A sample of n=7 males is taken. We know the sample mean = 315 watts and the sample standard deviation = 16 watts.

For a 99% confidence interval, the value of z is z=2.58.

We can calculate the confidence interval as:

$M-z\sigma/\sqrt{n}\leq\mu\leq M+z\sigma/\sqrt{n}\\\\315-2.58*16/\sqrt{7}\leq\mu\leq 315+2.58*16/\sqrt{7}\\\\315-15.6\leq \mu\leq 315+15.6\\\\299.4\leq\mu\leq 330.6$

The 99% confidence interval for the mean peak power after training is [299.4, 330.6]

------- = ------- and so 50x = 1200, or 5x = 120, or x = 24 (miles).

Iteru [2.4K]

Answer:

They will be able to.

Step-by-step explanation:

You first want to make sure the first three families have enough to eat.

$6\frac{1}{2} - 2\frac{7}{8} = 3\frac{5}{8}$

For further explanation look at the first image.

$3\frac{5}{8} > 2\frac{7}{8}$

Just to make sure

$3\frac{5}{8} - 2\frac{7}{8}=\frac{3}{4}$

For further explanation look at the second image.

The rest of the images show a model solution.
