You can use the factors of the volumes 24, 27 and 48:
For example:
8 by 3 by 1 is a total volume of 24
or if you know that 4 times 2 is 8:
4 by 2 by 2

A manager of a grocery store wants to determine if consumers are spending more than the national average. The national average i
strojnjashka [21]

The valid conclusions for the manager based on the considered test is given by: Option

<h3>When do we perform one sample z-test?</h3>

One sample z-test is performed if the sample size is large enough (n  > 30) and we want to know if the sample comes from the specific population.

For this case, we're specified that:

  • Population mean = \mu = $150
  • Population standard deviation = \sigma = $30.20
  • Sample mean = \overline{x} = $160
  • Sample size = n = 40 > 30
  • Level of significance = \alpha = 2.5% = 0.025
  • We want to determine if the average customer spends more in his store than the national average.

Forming hypotheses:

  • Null Hypothesis: Nullifies what we're trying to determine. Assumes that the average customer doesn't spend more in the store than the national average. Symbolically, we get: H_0: \mu_0 \leq \mu = 150
  • Alternate hypothesis: Assumes that customer spends more in his store than the national average. Symbolically H_1: \mu_0 > \mu = 150

where \mu_0 is the hypothesized population mean of the money his customer spends in his store.

The z-test statistic we get is:

z = \dfrac{\overline{x} - \mu_0}{\sigma/\sqrt{n}} = \dfrac{160 - 150}{30.20/\sqrt{40}} \approx 2.094

The test is single tailed, (right tailed).

The critical value of z at level of significance 0.025 is 1.96

Since we've got 2.904 > 1.96, so we reject the null hypothesis.

(as for right tailed test, we reject null hypothesis if the test statistic is > critical value).

Thus, we accept the alternate hypothesis that customer spends more in his store than the national average.

Answer:

4.) 40 Apps can be downloaded in 1 minute

5.) 0.2 or 2/10 of a miles can be traveled in 1 second

Step-by-step explanation:

4.)

So 12 seconds is = to 1/5 of a minute

So the question asks for 1 minute

This means that we need to perform 1/5 *5 to get 1 minute

If we multiply 5 to 1/5 minutes, we also need to multiply 5 to the apps

8 * 5 = 40

So that is how we solved the answer.

So DeAndre can download 40 Apps in 1 minute.

5.)

So he traveled 1/10 miles in 1/2 or 0.5 seconds.

This means we can multiply the seconds by 2 to get 1 second.

0.5 * 2 = 1

If we multiply the seconds by 2 we also need to multiply the miles traveled by 2.

So (1/10) * 2

The 2 can be rewritten as (2/1) because 2/1 is the same as 2

(2/1) * (1/10)

So we multiply straight out and get 2/10 miles traveled which can be simplified to 1/5 miles traveled.
