Question

The histogram above shows the hieghts (in cm) distribution of 30 people.

a.) determine the range of heights for this group of 30 people.

B.) list the mean/meadian class.

c.) determine the mean hieght of this group of 30 people. compare with a visual obervation of the histogram.

d.) determine the median height of this gorup of 30 people. compare witha visual observation of the histogram.

E.) does this data exhibit a normal or near - normal distribution? who or why not?

Heights of 30 people 5 139.5 149.5 159.5 169.5 179.5 189.5 199.5 Heights in cm www.analyzemath.com

Range = highest reading - lowest reading

= 199.5-139.5 = 60 cm

B) Median = 159.5 (exactly 15th)

C) To find mean

d) Median = 159.5

e) near normal as symmetrical but mean and median slightly vary

Hence right skewed
