Answer:
You will subtract these top 2
- 7 {a}^{2} + 3a - 9 - 7 {a}^{2} + 3a - 9
5 {a}^{2} - 6a - 45 {a}^{2} - 6a - 4
and this bottom one is your ANSWER
- 12 {a}^{2} - 110a - 22
Answer: t= 2.032
Step-by-step explanation:
Given : Sample size :
Sample mean :
Standard deviation :
Claim : The IQ scores of statistics professors are normally distributed, with a mean greater than 116.
Let be the mean scores of statistics professors.
Then the set of hypothesis for the given situation will be :-
As the alternative hypothesis is right tailed , thus the test would be right tail test.
Since the sample size is less than 30, therefore the test would be t-test .
The test statistics for the given situation will be :-
Hence, the value of the test statistic : t= 2.032
