Answer:
What problem
Step-by-step explanation:
there is no problem
Given:
n = 40, sample size
xb = $6.88, sample mean
σ = $1.92, population standard deviation
At 90% confidence interval, the expected range is
= [ 6.88 - 1.645*(1.92/√40), 6.88 + 1.645*(1.92/√40)]
= (6.38, 7.38)
Answer:
The 90% confidence interval is ($6.38, $7.38)
Answer:
A = 6 x 7
Step-by-step explanation:
To find the area of a parallelogram we use the equation of Area = base x height. In this case since the base is 6 and the height is 7, we plus in these numbers for the variables (b x h) to get the area.
