Answer: 1.509
Step-by-step explanation:
The formula of Margin of Error for (n<30):-

Given : Sample size : n= 22
Level of confidence = 0.99
Significance level : 
Using the t-distribution table ,
Critical value : 
Standard deviation: 
Then, we have

Hence, the margin of error for a 99% confidence interval for the population mean =1.509
C = -5
8c-6=2c-36
8c-2c=-36+6
6c=-30
Im pretty sure it would be 48 since the beginning number is 50 and A is 2 more down. and if 1 mark = 1 unit then i think it will be 48
