A researcher would like to examine how the chemical tryptophan, contained in foods such as turkey, can affect mental alertness.
A sample of n = 9 college students is obtained and each student’s performance on a familiar video game is measured before and after eating a traditional Thanksgiving dinner including roast turkey. The average score dropped by M = 14 points after the meal with SS = 1152 for the difference scores.
a. Is there is significant difference in performance before eating versus after eating? Use a two-tailed test with α = .05.
b. Compute r2 to measure the size of the effect.
c. Write a sentence demonstrating how the outcome of the test and the measure of effect size would appear in a research report.

Answer:
The quantity of Jennie's skin cell were not burned is 119.601 × .
Step-by-step explanation:
Given as :
The percentage of Jennie's skin cell were burned = 3 %
The quantity of Jennie's skin cell were burned = 3.7 ×
Let The quantity of Jennie's skin cell were not burned = x
Let Total quantity of whole skin cell = n
<u>Now, According to question</u>
The quantity of Jennie's skin cell were burned = Total quantity of whole skin cell × percentage of Jennie's skin cell were burned
i.e 3.7 × = n × 3 %
Or, 3.7 × = n ×
Or, n = 3.7 × ×
Or, n =
i.e n = 1.233 ×
Or, Total quantity of whole skin cell = n = 1.233 ×
<u>Now, Again</u>
∵ percentage of Jennie's skin cell were burned = 3 %
So, percentage of Jennie's skin cell were not burned = 100 % - 3 % = 97 %
so , The quantity of Jennie's skin cell were not burned = 97 % of Total quantity of whole skin cell
Or, x = × n
Or, x = × 1.233 ×
∴ x = 119.601 ×
So, The quantity of Jennie's skin cell were not burned = x = 119.601 ×
Hence, The quantity of Jennie's skin cell were not burned is 119.601 × . Answer
