Last school year, the student body of a local university consisted of 30% freshmen, 24% sophomores, 26% juniors, and 20% seniors

tino4ka555 [31]

Answer:

$\chi^2 = \frac{(83-90)^2}{90} +\frac{(68-72)^2}{72}+\frac{(85-78)^2}{78}+\frac{(64-60)^2}{60} = 1.66$

And the answer would be:

c. 1.66

Step-by-step explanation:

We need to conduct a chi square test

The statistic to check the hypothesis is given by:

$\sum_{i=1}^n \frac{(O_i -E_i)^2}{E_i}$

the observed values for this case are:

$Freshemen=83$

$Sophomores=68$

$Juniors = 85$

$Seniors= 64$

The expected values for this case are:

$Fres_E =0.3*300= 90$

$Sop_E =0.24*300= 72$

$Jun_E = 0.26*300 =78$

$Sen_E = 0.20*300= 60$

Then the statistic would be given by:

$\chi^2 = \frac{(83-90)^2}{90} +\frac{(68-72)^2}{72}+\frac{(85-78)^2}{78}+\frac{(64-60)^2}{60} = 1.66$

And the answer would be:

c. 1.66
