Answer:
Kindly check explanation
Step-by-step explanation:
Given :
Sample size, n = 30
Tcritical value = 2.045
Null hypothesis :
H0: μ = 9.08
Alternative hypothesis :
H1: μ≠ 9.08
Sample mean, m = 8.25
Samole standard deviation, s = 1.67
Test statistic : (m - μ) ÷ s/sqrt(n)
Test statistic : (8.25 - 9.08) ÷ 1.67/sqrt(30)
Test statistic : - 0.83 ÷ 0.3048988
Test statistic : - 2.722
Tstatistic = - 2.722
Decision region :
Reject Null ; if
Tstatistic < Tcritical
Tcritical : - 2.045
-2.722 < - 2.045 ; We reject the Null
Using the α - level (confidence interval) 0.05
The Pvalue for the data from Tstatistic calculator:
df = n - 1 =. 30 - 1 = 29
Pvalue = 0.0108
Reject H0 if :
Pvalue < α
0.0108 < 0.05 ; Hence, we reject the Null
Your Question;
The temperature in Bloomington on Sunday was 32.6°C. On Monday, the temperature changed by -8.25°C. What was the temperature on Monday?
My Answer;
If Monday was 8.25°C cooler than Sunday, and it was 32.6°C on Sunday.
We need to figure out the temperature on Monday, and it was 24.35°C
on Monday.
My Work;
32.6 + ( -8.25 ) = 24.35
Hope I helped,

Andrea was working at a factory that produced 13,455 cookies per week. They only worked for 5 days. How many cookies were made each day?
Equation: 13,455 / 5 = 2691 cookies
I didn’t know what you meant by explaining the first digit quotient but I did everything else.
10 hours.
If you multiply 2 1/2 by 4, the product is 10.
