Answer:

32% = 480

26% = 390

18% = 270

10% = 150

14% = 210

Step-by-step explanation:

1500(0.68) = 1020 = 1500 - 1020 = 480

1500(0.74) = 1110 = 1500 - 1110 = 390

1500(0.82) = 1230 = 1500 - 1230 = 270

1500(0.90) = 1350 = 1500 - 1350 = 210

For the last one, just add the percentages off and subtract the number by 100 to see what is left, then do the same with the number of people out of 1500 and that gives you the final number.

Answer:

$F=\frac{s^2_2}{s^2_1}=\frac{5.5}{2.5}=2.2$

Now we can calculate the p value but first we need to calculate the degrees of freedom for the statistic. For the numerator we have $n_2 -1 =16-1=15$ and for the denominator we have $n_1 -1 =16-1=15$ and the F statistic have 15 degrees of freedom for the numerator and 15 for the denominator. And the P value is given by:

$p_v =2*P(F_{15,15}>2.2)=0.138$

For this case the p value is highert than the significance level so we haev enough evidence to FAIL to reject the null hypothesis and we can conclude that the true deviations are not significantly different
