1. For the following scores, find the mean, median, and the mode. Which would be the most appropriate measure for this data set?

13 The classification of student major (accounting, economics, management, marketing, other) is an example of:

b) In order to calculate the mean or average for the governors and CEO’s, I added together all the figures and divided that sum by 4 since there

5. Give the standard deviation for the mean and median column. Compare these and be sure to identify which has the least variability?

1. By hand, compute the mean, median, and mode for the following set of 40 reading scores:

One-Sample T: Sleep Variable N Mean StDev SE Mean 95% CISleep 20 6.950 1.572 0.352 (6.214, 7.686)95% of students get between 6.2 hour to 7.69 hour of sleep.

Sample size for a given confidence level and margin of error (proportions). Poll articles. Hypotheses tests for a mean, and differences in means (independent and paired samples). Sample size and power of a test. Type I and Type II errors. You will be given a table of normal probabilities. You may wish to be familiar with the follow formulae and their application.

The mean was 4.23. The median was 2 and the mode was 0. The most appropriate measure of central tendency for this set of data is the mode. The mode is most appropriate because out of 1171 people 441 people had 0 prior arrests. The other numbers of arrests showed the next highest being 1 at 114 total people. This shows that the majority of those in the data set did not have a prior conviction.

For the education data, I must say to calculate the median, from high school to college graduate, the median would be the some college portion since it would be the middle. The median for the experimental group would be 11 and 34.4% and for the control group it would be 15 and 41.7%.

The customers in this case study have complained that the bottling company provides less than the advertised sixteen ounces of product. They need to determine if there is enough evidence to conclude the soda bottles do not contain sixteen ounces. The sample size of sodas is 30 and has a mean of 14.9. The standard deviation is found to be 0.55. With these calculations and a confidence level of 95%, the confidence interval would be 0.2. There is a 95% certainty that the true population mean falls within the range of 14.7 to 15.1.

Fry Brothers heating and Air Conditioning, Inc. employs Larry Clark and George Murnen to make service calls to repair furnaces and air conditioning units in homes. Tom Fry, the owner, would like to know whether there is a difference in the mean number of service calls they make per day. Assume the population standard deviation for Larry Clark is 1.05 calls per day and 1.23 calls per day for George Murnen. A random sample of 40 days last year showed that Larry Clark made an average of

To begin the statistical analysis of the data provided, we need to present the statistical description of it, take a general look at the means and medians for each sector and test the normal distribution of the data to see if we can undertake any further test.

In order to find out if the statement is true or should be rejected, we will use means of transport as one category and the other which would be compared is going to be expected grades at the end of the course. Around 36% of those who use public transport are expecting to receive a 1st class grade at the end of the year. While the same grade is expected by more than 43% students who use personal means of transport. Moreover, the mean grade expected by the whole class is 2.1 and 48% students who use public transport are expecting this grade, while 50% who use personal transport are expecting it. The lowest which is expected by all the students is a pass grade and 75% who expect it use public transport while only 25% of those who expect it are users of personal transport. Contrastingly, only 6.5% users of public transport expect a pass grade while 9.3% students who use a car or take a walk expect a pass grade. Thus, the statement can be considered as true.
