Question

Problem- 1

The following data shows the number of hours that 8 hospital patients slept following the administration of a certain anesthetic.

8, 7, 9, 11, 7, 6, 5, 7,

Find a 98% confidence interval for the average hours slept following the administration of the anesthetic for the sampled population. (round upto 2 decimals)

Consider the following data (which is also the data that you will be using in Problem #7 below):

8, 7, 9, 11, 7, 6, 5, 7,

problem -2 (a)

If you were to construct a normal probability plot by hand for the above data, what are the numerical values (in order) of the first five numbers that would go on the x-axis? Separate your answers with a comma. For example, if your data was the same as the data in the first example in Section 5.7 of the textbook, then you would enter the following numbers from Step a into the answer box (note that spaces don't matter): 66.2, 67.6, 68.7, 70.8, 71.7

(b)

If you were to construct a normal probability plot by hand for the above data, what are the numerical values (in order) of the first five numbers that would go on the y-axis? Separate your answers with a comma. For example, if your data was the same as the data in the first example in Section 5.7 of the textbook, then you would enter the following numbers from Step c (note that spaces don't matter): −1.28, −0.52, 0, 0.52, 1.28

(c)	Is it reasonable to assume that the above data come from a population that follows a normal distribution?
