Hello!

You divide the total time by the time unit for the slope

54 / 3 = 18

Multiply this by how height the cart goes

4 * 18 = 72

The answer is 72

Hope this helps!

Watching TV: In 2012, the General Social Survey asked a sample of 1326 people how much time they spent watching TV each day. The
Varvara68 [4.7K]

Answer:

We <em>fail to reject H₀ </em>as there is insufficient evidence at 0.5% level of significance to conclude  that the mean hours of TV watched per day differs from the claim.

Step-by-step explanation:

This is a two-tailed test.

We first need to calculate the test statistic. The test statistic is calculated as follows:

Z_calc = X - μ₀ / (s /√n)

where

  • X is the mean number of hours
  • μ₀ is the mean that the sociologist claims is true
  • s is the standard deviation
  • n is the sample size

Therefore,

Z_calc = (3.02 - 3) / (2.64 /√(1326))

           = 0.2759

Now we have to calculate the z-value. The z-value is calculated as follows:

z_α/2 = z_(0.05/2) = z_0.025

Using the p-value method:

P = 1 - α/2

  = 1 - 0.025

  = 0.975

Thus, using the positive z-table, you will find that the z-value is

1.96.

Therefore, we reject H₀ if | Z_calc | > z_(α/2)

Thus, since

| Z_calc | < 1.96, we <em>fail to reject H₀ </em>as there is insufficient evidence at 0.5% level of significance to conclude  that the mean hours of TV watched per day differs from the claim.
