From the question we are told that
The average cost is
![\mu = \$ 200 000.00](https://img.qammunity.org/2021/formulas/mathematics/college/j4cwo6uley70vg5qyulh6sdd9wgplibs2o.png)
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
![\alpha = (100 - 95 ) \%](https://img.qammunity.org/2021/formulas/mathematics/college/cwt2gythg7waqtc0ojcgglfkjp7yf95wso.png)
=>
![\alpha = 0.05](https://img.qammunity.org/2021/formulas/mathematics/college/445n2djo6b5zbv5df68kz5tjhh2puf9bol.png)
