Well d = distance. r = Rate. t = Time. Distance = Rate x Time.
To get r by itself you will divide rt by t. Now you have to do that to the other side. so d/t = r. So B :)
Using the t-distribution, the t-statistic for the two-sided test would be of t = 0.7.
<h3>What is the test statistic for a t-distribution hypotheses test?</h3>
The test statistic is given by:

The parameters are:
is the sample mean.
is the expected value.
- s is the standard deviation of the sample.
The values of the parameters are given as follows:
.
The sample mean is:

Hence the test statistic is:


t = 0.7.

Answer: 13 minutes
Step-by-step explanation:
( 0 + 2 + 10 + 8 + 20 + 12 + 30 + 7 + 40 + 1)/10 = 130/10 = 13
Hope this helps!
Answer:
6.5
Step-by-step explanation:
To round 6.48 to nearest tenth means to round the numbers so you only have one digit in the fractional part.
