- Find the positive geometric mean between 4 and 64.Matt thinks that he has a special relationship with the number 1. In particular, Matt thinks that hewould roll a 1 with a fair 6-sided die more often than you'd expect by chance alone. Suppose p is the trueproportion of the time Matt will roll a 1.(a) State the null and alternative hypotheses for testing Matt's claim. (Type the symbol "p" for thepopulation proportion, whichever symbols you need of "<", ">", "=", "not =" and express any values as afraction e.g. p = 1/3)HH.(b) Now suppose Matt makes n = 46 rolls, and a 1 comes up 10 times out of the 46 rolls. Determine the P-value of the test:P-value =(c) Answer the question: Does this sample provide evidence at the 5 percent level that Matt rolls a 1 moreoften than you'd expect?(Type: Yes or No)A pharmacist received a prescription for a patient with rheumatoid arthritis calling for eight divided powders. The contents of which were to weigh 1 gram. To check his skill, he removed the contents from each paper after filling the prescription by the block and divide method. Then each of the divided powders were weighed as: 1.05, 0.89, 0.98, 1.02, 1.01, 0.94, 1.03 and 0.99. 5. From the computed arithmetic mean, what will be the computed percentage error. 6. What is the summation of the differences of the values of x? * 7. What is the computed mean deviation? * 8. What is the summation of the square of the differences of the values of x? * 9. What will be the denominator used in the formula in the computation for the standard deviation in this activity? 10. What is the computed standard deviation?

- We wish to demonstrate that the average time to graduate from school is afected by the students who have taken AP calculus in hgh school. Specially, we wish to demonstrate the students who have taken AP calculus in high school graduate an average of more than .25 years sooner than students who have not taken AP calculus in high school. If we let μ1 denote the average time to graduate for students who have not taken AP calculus and μ2 dentoe the average time to graduate for students who have taken AP calculus, what is the apropriate null hypothesisExpress the null and alternative hypotheses in symbolic form for this claim: the mean weight of male dancers in a local modern dance company is less than 174 lbs. Note that the mean weight in the sample taken is 165 lbs.H0:μH1:μUse the following codes to enter the following symbols: ≥ enter >= ≤ enter <= ≠ enter !=If your numerical answer is NOT an integer, put it in percentage and rounded to 2 decimal places. For example, if the answer is 0.22575 , you have to put 22.58% in the box. DO NOT FORGET TO PUT THE PERCENT (%) SIGN AT LAST. Putting only 22.58 without the trailing percent sign will be assessed as a wrong answer! You must NOT type any other symbol, space, operator, fraction etc in the box. Suppose, you are running an experiment that has two outcomes, namely 'success' and 'failure'. You intially don't know the probability of success in a single experiment. But you know that, if you continue to run the experiment several times, the expected number of experiment required for the first success is 8. What is the standard deviation of the number of experiments required for the first success?
