Harlamova29_29 [7]

Answer: 5 benches and 23 students

Step-by-step explanation:

I will answer in English.

We have E students and B benches.

If we sit 4 students per bench, we have 3 students left.

then:

E = 4*B + 3

And if we sit 5 students per bench, there are two places with no students sited.

E = 5*B - 2

now we can replace the E in the second equation with the right part in the first equation:

4*B + 3 = 5*B - 2

3 + 2  = 5*B - 4*B

5 = B

So we have 5 benches, and:

E = 4*5 + 3 = 23 students.

A group of 26 canadians were randomly selected among a local group of fitness enthusiasts to participate in an innovative fitnes
Lady_Fox [76]

The appropriate statistical procedure to use here is a two-tailed hypothesis test for the population mean

What is standard deviation?

  • The term "standard deviation" (or "σ") refers to a measurement of the data's dispersion from the mean.
  • A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

Explanation:

  • Since we are interested in comparing here the mean heart rate for Canadians who participated in this fitness program, to that of the national average,
  • We have to have to conduct a hypothesis test here for sample mean
  • Since we are not trying to find the true population mean based on the sample mean, we do not have to construct a confidence interval
  • As the sample size, n = 26 < 30,therefore we will use the t-test instead of the z-test.

Therefore,  A one-sample t-test for means' is the correct choice.
