Question

For a data set obtained from a sample of size n = 144 with x¯=48.75, it is known that σ = 4.8.

For a data set obtained from a sample of sizen= 144 withx = 48.75, it is known that o = 4.8.
(a) What is the point estimate of u?
u= i
(b) Find z score coresponding to a 95% confidence level, za/2. Recall that (1- a)100% = 95%.
Give your answer with two decimal places.
(c) Construct a 95% confidence interval for u.
Round the answers to four decimal places.
<p< i
(d) What is the margin of error in part (c)?
Round the answer to four decimal places.
E= i
