Answer:
The correct option is the second option
Step-by-step explanation:
From the question we are told that
The average cost is [tex]\mu = \$ 200 000.00[/tex]
The sample size is n = 65
The upper limit of the 95% confidence interval is $1050.00
The lower limit of the 95% confidence interval is $850.00
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
