Answer: b. 0.98
Step-by-step explanation:
The formula to find the maximum error of the estimated mean :
(1)
, where
= standard deviation
n= Sample size
z* = Critical z-value.
As per given , we have

n=100
Critical value for 95% confidence interval = z*=1.96
Put these values in the formula (1), we get


Hence, the maximum error of the estimated mean quality for a 95% level of confidence is 0.98.
Therefore , the correct answer is b. 0.98 .
The slope represents the the number of hours after the sunrise, and the y intercept represents the temperature
The linear function would y=4x+4
6.) y=4+ 10/5x
7.) y= -5 -3x
0.825200
(correct me if I’m wrong)
