Use the following sample data to answer the next question. Use a 0.05 significance level and the observed frequencies of 207 drownings at the beaches of a randomly selected coastal state to test the claim that the number of drownings for each month is equally likely.

Listed below are times (in minutes and seconds) that a statistics instructor recorded while riding a bicycle for five laps through each mile of a 3-mile loop. Use a 0.10 significance level to test the claim that the samples are from populations with the same median. What do the data suggest? Mile 1 Mile 2 Mile 3 3:18 3:25 3:31 3:14 3:30 3:31 3:15 3:25 3:35 3:20 3:26 3:28 3:16 3:24 3:27 First determine the null and alternative hypotheses. Choose the correct answer below. O A. Ho: The samples come from populations with equal medians. H₁: The samples come from populations with medians that are not all equal. O B. Ho: The samples come from populations with means that are not all equal. H₁: The samples come from populations with equal means. O C. Ho: The samples come from populations with medians that are not all equal. H₁: The samples come from populations with equal medians. O D. Ho: The samples come from populations with equal means. H₁: The samples come from populations with means that…

Find the​ range, variance, and standard deviation for the given sample​ data, if possible. If the measures of variation can be obtained for these​ values, do the results make​ sense? Biologists conducted experiments to determine whether a deficiency of carbon dioxide in the soil affects the phenotypes of peas. Listed below are the phenotype​ codes, where 1 equals ​smooth-yellow, 2 equals ​smooth-green, 3 equals wrinkled ​yellow, and 4 equals ​wrinkled-green.   a. The range of the sample data is ​(Type an integer or a decimal. Do not​ round.)   b. the standard deviation of the sample data is ​(Round to one decimal place as​ needed.)   c. The variance of the sample data is ​(Round to one decimal place as​ needed.)
