Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.

Find the standardized test statistics Calculat p value State conclusion

A researcher claims that the stomachs of blue crabs from Location A contain more fish than the stomachs of blue crabs from Location B. The stomach contents of a
sample of 15 blue crabs from Location A contain a mean of 198 milligrams of fish and a standard deviation of 37 milligrams. The stomach contents of a sample of 11 blue
crabs from Location B contain a mean of 180 milligrams of fish and a standard deviation of 45 milligrams. At a = 0.05, can you support the researcher's claim? Assume
the population variances are equal. Complete parts (a) through (d) below.

Find the variance, standard deviation, and range for your data. Find the five-number summary and determine (mathematically) if there are any outliers. Construct a 95% confidence interval for the mean of your data. You are allowed to use the calculator for the calculations but you must provide me with the 30 data values you obtain in a neat, organized manner, preferably in a spreadsheet. Also, be sure to provide the source of your data. When you provide the answers to the questions above please use the correct symbols and notation.…
