The following data were used to construct the histograms of the number of days requiredto fill orders for Dawson Supply, inc., and J.C. Clark Distributors (see Figure 3.2).Dawson Supply Days for Delivery: 11 10 9 10 11 11 10 11 10 10Clark Distributors Days for Delivery: 8 10 13 7 10 11 10 7 15 12Use the range and standard deviation to support the previous observation that DawsonSupply provides the more consistent and reliable delivery times

Rhenz scored 32 points on their Math summative test. The following data are the summative test scores of Grade 10 Competence in Math. He wants to identify the percentage of his score among the class' scores. Construct a frequency distribution table. Interpret results and formulate conclusion. Compute the percentile rank of grouped data. Use the formula below.

Are the snow conditions a factor in the number of visitors at a ski resort? The table below shows data that was collected. Hard Packed Machine Made Powder 2457 1401 1708 1484 1895 2193 2334 1849 2803 1816 1870 1842 1792 1873 2969 2219 989 1791 1504 1917 2143 1265 1881 1545 2341 1531 Assume that all distributions are normal, the three population standard deviations are all the same, and the data was collected independently and randomly. Use a level of significance of a = 0.05. Ho: µi = µ2 = µ3 H1: At least two of the means differ from each other. 1. For this study, we should use Select an answer v 2. The test-statistic for this data = (Please show your answer to 3 decimal places.) 3. The p-value for this sample = (Please show your answer to 4 decimal places.) 4. The p-value is Select an answer 5. Base on this, we should Select an answer v hypothesis 6. As such, the final conclusion is that... O There is insufficient evidence to support the claim that snow conditions is a factor in the…

Calculate the mean and standard deviation for the two variables separately.
