Answer: 94, 9
Explanation:
The formula for calculating the margin of error is expressed as
margin of error = (upper value - lower value)/2
From the information given,
upper value = 103
lower value = 85
margin of error = (103 - 85)/2
margin of error = 9
To find the sample mean, we would apply the formula below;
sample mean = upper value - margin of error
sample mean = 103 - 9
sample mean = 94
