Step-by-step explanation:

Given that many couples believe that it is getting too expensive to host an "average" wedding in the United States.

Population mean =24066

Sample mean =  23224

Sample size = 40

Sample std dev = 2903

Since sample std dev is known, we use t critical value.

df =39

Sample mean follows a normal distribution with mean = 23224, and std dev =

t critical value = 2.023

Margin of error = 2.023*459.005

Confidence interval

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

40 x 50 = 2000
