A scientist who studies teenage behavior was interested in determining if teenagers spend more time playing computer games then
natita [175]

Answer:

greater than 0.10

Explanation:

The null hypothesis is:

H_{0} = 10.2

The alternate hypotesis is:

H_{1} > 10.2

Our test statistic is:

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the statistic, \mu is the mean, \sigma is the standard deviation and n is the size of the sample.

We have that:

t = 0.45

We are testing if X is greater than 0.45, so our pvalue is 1 subtracted by the pvalue of z = t = 0.45.

z = 0.45 has a pvalue of 0.6736

1 - 0.6735 = 0.3264

So our pvalue is 0.3264, which is greater than 0.10.

So the correct answer is:

greater than 0.10

What is. the units of velocity
natta225 [31]

Speed and velocity are both measured using the same units. The SI unit of distance and displacement is the meter. The SI unit of time is the second. The SI unit of speed and velocity is the ratio of two — the meter per second.
