Question
Shade the sampling distribution curve with the correct critical value(s) and shade the critical regions. The
arrows can only be dragged to z-scores that are accurate to 1 place after the decimal point (these values
correspond to the tick marks on the horizontal axis). Select from the drop down menu to shade to the left,
to the right, between or left and right of the z-score(s).
Shade: Left of a value
Click and drag the arrows to adjust the values.

Test the claim that the mean lifetime of a
certain kind of safari vehicle engine is greater
than 227,392 miles. A sample of 39 engines
show a mean of 233,274 miles and a
population standard deviation, o, of 14,000
miles. (Assume that the population standard
deviation is known.) Test the claim using a 1%
level of significance.
What are the correct hypotheses? (Select the
correct symbols and use decimal values not
percentages.)
Ho: Select an answer v
miles
H;: Select an answer v
miles
Original Claim = Select an answer v
Based on the hypotheses, find the following:
Critical value =
(Round to two decimal places.)
Z-score =
(Round to two decimal places and show work in the "show work" box below.)
p-value -
(Round to four decimal places and show work in the "show work" box below.)
