Find the

a. Mean b. median c. mode

For the mean and the median, round each answer to one more decimal place than that used for the observations.

Router Horsepower. In the article "Router Roundup" T. Kleck reported on tests of seven fixed-base routers for performance, features, and thandling. The following table gives the horsepower (hp) for each of the seven routers tested.

1.752.252.252.251.752.001.50

Short Answer

a)2hpb)2.00hpc)2.25hp

Step by step solution

01

Step 1. Given information.  

We have given data:1.752.252.252.251.752.001.50

02

Step 2. Mean of the data.  

Mean ==SumofobservationNumberofobservation

=1.75+2.25+2.25+2.25+1.75+2.00+1.507=1.964285714=2hp

03

Step 3. Median of the data.  

Arrange the data in increasing order : 1.50,1.75,1.75,2.00,2.25,2.25,2.25

The number of observation is 7.

The median is the middle observation in the ordered list.

Medianlocalid="1651338288085" =2.00hp

04

Step 4. Mode of the data.  

The greatest frequency is the mode of the data set.

The mode of the given data set is2.25hp.

How many standard deviations to either side of the mean must we go to ensure that for any data set, at least 95%of the observations lie within?

Sickle Cell Disease. A study published by E. Anionwu et al. in the British Medical Journal (Vol. 282, pp. 283-286) examined the steady-state hemoglobin levels of patients with three different types of sickle cell disease: HB SC. HB SS. and HB ST. Use the following boxplots to compare the hemoglobin levels for the three groups of patients, paying special attention to center and variation.

Copperhead and Tiger Snakes. S. Fearn et al. compare two types of snakes in the article 鈥淏ody Size and Trophic Divergence of Two Large Sympatric Elapic Snakes in Tasmania鈥� (Australian Journal of Zoology, Vol. 60, No. 3, pp. 159-165). Tiger snakes and lowland copperheads are both large snakes confined to the cooler parts of Tasmania. The weights of the male lowland copperhead in Tasmania have a mean of 812.07 g and a standard deviation of 330.24 g; the weights of the male tiger snake in Tasmania have a mean of 743.65 g and a standard deviation of 336.36 g.
a. Determine the z-scores for both a male lowland copperhead snake and a male tiger snake whose weights are 850 g.
b. Under what conditions would it be reasonable to use z-scores to compare the relative standings of the weights of the two snakes?
c. Assuming that a comparison using z-scores is legitimate, relative to the other snakes of its type, which snake is heavier?
