Suppose the tree growers asked 10 different questions about Christmas tree preferences in an effort to find differences between urban and rural residents. Explain why it would be unwise to perform 10 different 2-sample significance tests (α = 0.05) on their data and conclude that any significant result establishes a difference between the two groups.

The results will be very confusing as you will be concluding different results for each question. This will also require lot of time. Also drawing a single conclusion will be very difficult. An alternate could be to use matched pair t test.

Step-by-step explanation:

Two sample t test is used to compare means of two independent group

Matched pair is used to find out if there is difference in means of two matched sets of a data.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
