Count the total number of squares.

There are 10 by 10 of them or:

\sf 10\cdot 10=100

So there are a total of 100 squares, now count the shaded squares.

\sf 4\cdot 4=16

There are 16 shaded squares out of 100, this is a fraction:

\sf\dfrac{16}{100}=\boxed{\sf 0.16}

So your answer is C.

Using traditional methods it takes 107 hours to receive an advanced flying license. A new training technique using Computer Aide
Degger [83]

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 \mu = <u><em>average training time to receive an advanced flying license</em></u>

So, Null hypothesis, H_0 : \mu \geq 107 hours     {means that the new technique doesn't reduce training time}

Alternate Hypothesis, H_A : \mu < 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.
