Answer:
The 90% confidence interval for the population standard deviation waiting time for an oil change is (3.9, 6.3).
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for the population standard deviation is:

The information provided is:
<em>n</em> = 26
<em>s</em> = 4.8 minutes
Confidence level = 90%
Compute the critical values of Chi-square as follows:


*Use a Chi-square table.
Compute the 90% confidence interval for the population standard deviation waiting time for an oil change as follows:


Thus, the 90% confidence interval for the population standard deviation waiting time for an oil change is (3.9, 6.3).
1. -1•5•5 or also -1•5²
2. -1•7•7 -1•7²
3. -1•7
4. -1•13
5. -1•2•2•2•3 -1•2³•3
6.-1•2•2•2•2•3 -1•2^4•3
7. -1•2•2•2•3•7 -1•2³•3•7
Both factorization are correct it just depends on your teacher how she/he wants you to write it.
Hi there!
Pretty much, more means to add, so when you said, "10 more than 36", we immediately think addition. :)
36 + 10 = 46, right?
So, your answer is 46 :)
Hope this helps!
