Answer:
25.4, 28.6
Step-by-step explanation:
Given parameters
sample size, n = 24
sample mean, X = 27
population standard deviation, s = 3
critical value, Zα/2, where α = 0.01
99% confidence Interval, CI, is given as follows
CI = X ± Zα/2 × (s/√n)
Zα/2 = Z0.01/2 = Z0.005 = 2.576
CI = 27 ± 2.576 × (3/√24)
= (25.42 ,28.57)
Answer: 59.342
Step-by-step explanation:
The chi-square critical values are used to find the confidence interval for σ.
Left critical value = 
[i.e. chi-square value from chi-square table corresponding to degree of freedom n-1 and significance level of 
]
To find : left critical value for 95% confidence interval for σ with n = 41.
Significance level : 
degree of freedom = 41-1=40
Now, the left critical value for 95% confidence interval for σ with n = 41 is the chi-square value corresponding to degree of freedom n-1 and 
=59.342 [from chi-square table ]
