A supervisor records the repair cost for 23 randomly selected stereos. A sample mean of $91.82 and standard deviation of $16.84
Assoli18 [71]

Answer: 2.508

Step-by-step explanation:

As per give , we have

Sample size : n= 23

Degree of freedom : df= n-1=22

significance level : \alpha: 1-0.98=0.02

Since , the sample size is small (n<30) and population standard deviation is unknown.

So , we use t-test.

For confidence interval , we find two-tailed test value.

Critical t-value : t_{\alpha/2, df}=t_{0.01,22}

=2.508  [using students's t-critical value table]

Hence, the critical value that should be used in constructing the confidence interval = 2.508
