Answer:
B. There is not sufficient evidence at the 0.02 level of significance that the new technique reduces training time.
Step-by-step explanation:
We are given that using traditional methods it takes 107 hours to receive an advanced flying license.
A researcher believes the new technique may reduce training time and decides to perform a hypothesis test.
Let
= <u><em>average training time to receive an advanced flying license</em></u>
So, Null hypothesis,
:
107 hours {means that the new technique doesn't reduce training time}
Alternate Hypothesis,
:
< 107 hours {means that the new technique may reduce training time}
Now, it is stated that after performing the test on 50 students, the researcher decides to reject the null hypothesis at a 0.10 level of significance.
As we know that if the test statistics value is rejected at a 10% level of significance, then it must not be rejected at the 0.02 level of significance.
This means that there is not sufficient evidence at the 0.02 level of significance that the new technique reduces training time because our null hypothesis has not been rejected.
The measures of central tendency, fancy words for the middle, are

Answer:
down below
Step-by-step explanation:
The line slopes downwards as we move from left to right. The vertical intercept is 5. The gradient measures the steepness of the line. A large positive value of m means the graph increases steeply as you move from the left to the right. Answer.
