3. The distribution of undergraduate grade point averages at a large university is approximately normal with a mean of 2.8 and a standard deviation of 0.4.

·  How were measures of central tendency used in the study? Did the study use the most appropriate measure of central tendency for the given data? Why or why not?

The mean for the median column of the worksheet is 3.6Yes, the estimate is centered about the parameter of interest.

Therefore, the arithmetic mean is not useful for evaluating distributions. Conversely, the expected value 14.69 calculated above is an average possible outcome and is weighted by probability, and is a more accurate tool in evaluating

But why below 70? This score has been chosen as a result of normal distribution, meaning that it is directly linked and

Mean would be the most appropriate measure of central tendency to describe this data. This is because the mean is the average of all scores in the data set. If Dr. Williams were to graph the data into a bell shaped distribution, then the mean would be in the center where most of the scores are located. The mean is calculated using all information of the data set, and is the best score to use if you want to predict an individual score.

Determine if the outcome is unusual. Consider as unusual any result that differs from the mean by more than 2 standard

If the population average were in fact 8.2 days it is difficult to reasonably expect a sample average to be 4 standard errors above the population average by chance.

All of us want great looking nails, but at what price. The majority of folks do not realize that normal nail polish is made using formaldehyde and other sorts of harsh toxic chemicals. It is no longer arduous to obtain organically produced merchandise and that includes nail varnish. Not only is organically produced nail polish better for you, it is also better on the ecosystem, it's long-lasting and earth-friendly. Also, you're going to truly feel fantastic about your elegant nails, but you will know you are not going to be adding harsh chemical contaminants to the

distribution of these scores is normal, 99% of the scores are between 232 and 748 and 0.5% of the

Conclusion : Fails to reject the null hypothesis. The sample does not provide enough evidence to support the claim that mean is significantly different from 12 .

The mean, average of the population, the standard deviation, deviation in the sample, and a histogram, a graph to show the percentage of the population, was prepared. The means calculated as follows: blue 0.2072, orange 0.2271, green 0.1852, yellow 0.1165, red 0.1448, and brown 0.1192. The histogram was bell shaped with three outliers, numbers outside the given range, of 55 candies, or one bag.

With a P-value of 0.00, we have a strong level of significance. No additional information is needed to ensure that the data given is accurate.

The market for wax-based shoe polishes is dramatically shrinking, due in part to the latest product developments on the market (specifically the introduction of liquid shoe polishes) and to the altering consumer methods of use of shoe care

To meet the needs of this project, we used a lot of situations similar methods. I'll analysis the advantages and disadvantages of each method.
