A quality control expert at a local dairy claims that its cartoons contain more than 64oz of milk a sample of 15 cartoons reveals a mean of 65 and 1.1 oxs respectively. At the 1% level, does the appropriate hypothesis support his claim? find and interpret the p value

The manufacturer of a new eye cream claims that the cream reduces the appearance of fine lines and wrinkles after just 14 days of application. To test the claim, 10 women are randomly selected to participate in a study. The number of fine lines and wrinkles that are visible around each participant’s eyes is recorded before and after the 14 days of treatment. The following table displays the results. Test the claim at the 0.05 level of significance assuming that the population distribution of the paired differences is approximately normal. Let women before the treatment be Population 1 and let women after the treatment be Population 2. Number of Fine Lines and WrinklesBefore    11    14    13    12    15    14    9    11    11    14After    10    14    11    13    13    13    8    12    10    15 Step 1 of 3 :  State the n ull and alternative hypotheses for the test.

Use the attached image to answer the question:   Use the data above to construct a bivariate table and explore if there is an association between one’s education and attitudes toward cohabitation. Is there an association? Describe the pattern of association.   Assuming that this is a random sample, test a hypothesis (use α = 0.01) that there is an association between one’s education and attitudes toward cohabitation in the population. Show all your work (state the hypotheses, find the critical value, compute the test statistics, state a conclusion) and write one sentence summarizing the results. (Extra-credit: find the p-value).   Is this association weak, moderate or strong? Compute and interpret the appropriate statistic.

In a study of store checkout​ scanners, 1234 items were checked and 21   checked items were overcharges. Use a 0.05 significance level to test the claim that with​ scanners, 1% of sales are overchanrges.​ (Before scanners were​ used, the overcharge rate was estimated to be about​ 1%). a. Define the parameter     A. p​ = The proportion of all sales that are incorrect   B. p​ = The proportion of all sales that are overcharges   C. mu   ​= The mean number of sales that are overcharges   D. mu   ​= The proportion of all sales that are undercharges   b. State the null and alternative hypotheses     A. Upper H 0 : p equals 0.01 Upper H 1 : p not equals 0.01     B. Upper H 0 : p equals 21    Upper H 1 : p less than 21     C. Upper H 0 : p greater than 0.01 Upper H 1 : p equals 0.01     D. Upper H 0 : mu not equals 0.01 Upper H 1 : mu equals 0.01     c. Calculate the sample proportion ModifyingAbove p…
