Assist the statistician to construct a box whisker plot for the data on ``Expenditures per household living in Halifax’’ by computing the following: only the data on Halifax They are not different questions it's part of it!! thank you!

The average American gets a haircut every 43 days. Is the average larger for college students? The data below shows the results of a survey of 11 college students asking them how many days elapse between haircuts. Assume that the distribution of the population is normal. 38, 37, 38, 45, 53, 55, 35, 37, 35, 41, 38 What can be concluded at the the α = 0.05 level of significance level of significance? For this study, we should use? Select an answer: t-test for a population mean?  z-test for a population mean?         The null and alternative hypotheses would be:              H0:H0?   p  or  μ  Select an answer > = ≠ ≤ < ≥                H1:H1?  μ  or p  Select an answer ≠ ≥ > ≤ = <         2. The test statistic ? t z  =  (please show your answer to 3 decimal places.)           The p-value = _______ (Please show your answer to 3 decimal places.)           The p-value is? > or  ≤  α      3.  Based on this, we should??

You may need to use the appropriate appendix table or technology to answer this question. The following results are for independent random samples taken from two populations. Sample 1 Sample 2 n1 = 20 n, = 30 X1 = 22.7 X2 = 20.1 s, = 2.3 2 = 4.6 (a) What is the point estimate of the difference between the two population means? (Use x, - x,.) 2.72 (b) What is the degrees of freedom for the t distribution? (Round your answer down to the nearest integer.) 48 (c) At 95% confidence, what is the margin of error? (Round your answer to one decimal place.) 1.9 (d) What is the 95% confidence interval for the difference between the two population means? (Use x, - Round your answers to one decimal place.) .6 to 4.4

nd the 30th and 98th percentile values cf a normal variable with Mean of 12_and Variance of 30 Anot This I NEED PARTBI b), Suppose we sample 3 items from this population. Find the variables that correspond to the central 85% Confident Interval range of the sum of these 3 samples.

Measures average (central tendency/ location). The test scores of a class of students are presented by the following date set: 88, 86, 66, 50, 65, 90, 98, 100, 76, 89, 66, 89, 88, 90, 91, 90, 40, 77, 82, 86 Note: Recall the definitions of measures of central tendency. 10Extra: Subtract 5 points from each score. How would requested measures of average change? Generalize and make a conjecture. Find and compare ranges / midranges of both data sets. Find the mean, median, and mode. Mean, median, mode
