I'm not going to dignify this question with a response. xD
Answer:
16÷25=0.64
0.64x2 =1.28
Step-by-step explanation:
Answer:
a)
b) For this case since the value 32.5 is in the confidence interval obtained then we can't conclude that the statement by Nielsen is wrong
Step-by-step explanation:
Information given
represent the sample mean
population mean (variable of interest)
s=23.1 represent the sample standard deviation
n=75 represent the sample size
Part a
The confidence interval for the mean is given by the following formula:
(1)
The degrees of freedom are given by:
Since the Confidence is 0.95 or 95%, the value of
and
and the critical value would be
Now we have everything in order to replace into formula (1):
Part b
For this case since the value 32.5 is in the confidence interval obtained then we can't conclude that the statement by Nielsen is wrong
