Round to the nearest thousands (underlined and bolded): 9<u>1</u>800
Look at the place value to the right of the one you are solving for (hundreds place in this case). The value is 8, which is greater than 5. Because it is greater than 5, you round up
91800 rounded to the nearest thousand is 92000.

Answer: Correct critical value = 2.2622
Step-by-step explanation:
Confidence interval for population mean when population standard deviation is unknown:
, where = sample mean, n= sample size, s= sample standard deviation, = two-tailed t value.
As per given: n= 10
degree of freedom : df = n-1=9
Critical t-value :
So, the 95 percent confidence interval estimate for the mean :
The 95 percent confidence interval estimate for the mean:(190.14, 295.06)
