Step-by-step explanation:

To answer this question, we need to use the z-score formula written below:

\frac{x-pop. mean}{stan. devi.}

Now we'll just plug in the numbers and solve.

History:

\frac{85-65}{5}  = 4

Biology:

\frac{90-85}{10} =0.5

As we can see, history wields a higher z-score than biology, thus leaving us with option D. History

Answer:

t = 3.156

Step-by-step explanation:

N = 9

Please check attachment for the table

ED = 89

ED² = 1587

Bar D = 89/9

= √14283-7921/81

= √78.5432

S = 8.8625

= 9.8889/3.1334

= 3.156

From the calculations above, the calculated test statistic t is = 3.156.
