1 answer:

4 0

To solve the problem shown above you must apply the following proccedure:

1. Let's call:

x: a number.
f: the factor.

2. Then, you have:

√fx=3√x

3. You must clear the factor "f" to calculate its value, as below:

√fx=3√x
(√fx)²=(3√x)²
fx=9x
f=9x/x

4. Then, the factor is:

f=9

Answer:

b) independent samples t-test

$t=\frac{(5.92 -5.74)-(0)}{\sqrt{\frac{1.88^2}{5}}+\frac{1.81^2}{5}}=0.154$

$p_v =2*P(t_{8}>0.154) =0.881$

So with the p value obtained and using the significance level given $\alpha=0.05$ we have $p_v>\alpha$ so we can conclude that we have enough evidence to FAIL to reject the null hypothesis, and we can said that at 5% of significance the mean of the group 1 (boys) is NOT significantly different than the mean for the group 2 (Girls).
