Q 1: Select what If the following statements are true or false: (grades 5 ) CLO7: C1 )

Q2 : If you have two samples for the grades of students obtained in some courses in the Faculty of Law as follows:

                                                                             (Grades 5 ( 1) CLO 8: C2, CLO 9: C3 )

Required:

1- Calculate the measures of central tendency ( arithmetic mean, median, mean) for each student.

2- Calculate scattering parameters (range, variance, standard deviation, variation coefficient) per student.

A concrete masonry unit has actual gross dimensions of 7-5/8” x 7-5/8” x 7-5/8”. The unit is tested in a compression machine with the following results:

            Failure load = 98,000 lb

            Net volume = 348.1 in³

1. Is the unit categorized as solid or hollow?
2. Calculate the gross area compressive strength.
3. Calculate the net area compressive strength.

please answer by typing, i will rate your answer.

a. Find the two first partials ?? and ?? of the following function. ?(?, ?) = ?³?⁵ + ?^4x sin(?)

b. Find and classify all critical points of ?(?, ?) = ?³ − 3? + ?² − 4? + 7.

c. Maximize and minimize ?(?, ?) = 3? + ? + 33 subject to ?² + ?² = 40.

1. The amount of income spent on housing is an important component of the cost of living. The total costs of housing for homeowners might include mortgage payments, property taxes, and utility costs (water, heat, electricity). An economist selected a sample of 20 homeowners in New England and then calculated these total housing costs as a percent of monthly income, five years ago and now. The information is reported below. At the .05 significance level, is it reasonable to conclude the percent is less now than five years ago?

Really important: Use Excel as described in “How to perform two-sample hypothesis tests” in the content area to do this problem. You can copy the table below into an Excel file—no need to type it. Use the same Excel file that you used for the previous problem, but put each problem on a separate worksheet (you move to another worksheet by clicking the tabs at the bottom). Please name each worksheet by right-clicking on the tab, selecting Rename, and typing the problem number. This is chapter 11, problem 4, so call it “11-4.”

a. State the null and alternate hypotheses.

b. Select alpha.

c. Select the test statistic.

d. Formulate the decision rule.

e. What is the value of the test statistic?

f. Determine and interpret the effect size and p-value.

g. Draw conclusions based on statistical and practical significance.

Markov Chains:

A small town purchases salt by railroad-car loads to be used for melting ice and snow on the roads during the winter. One railroad car holds twelve tons of salt. The amount of salt used in any one storm depends upon the severity and duration of the storm. Past experience shows that, of the storms which are serious enough to call for any salt, some will require only one pass of the salt trucks, some will require two passes, and a few will require three passes. Each pass (a complete coverage of all of the streets of the town) consumes five tons of salt. Also from past experience, it has been estimated that 50 percent of the storms are one-pass storms, 40 percent are two-pass, and 10 percent are three-pass. The initial supply of salt at the beginning of winter is five railroad cars, or sixty tons. Construct a Markov chain model to show the consumption of salt over time, where time is measured discretely in the number of storms since the beginning of winter.

Please give the answer in either Matrix Form or as a Transition Diagram for a thumbs up. Thank you

The mean cost of a meal for two in a mid-range restaurant in Tokyo is $40 (Numbeo.com website, December 14, 2014). How do prices for comparable meals in Hong Kong compare? The DATAfile HongKongMeals contains the costs for a sample of 42 recent meals for two in Hong Kong mid-range restaurants. Click on the datafile logo to reference the data.

You may need to use the appropriate appendix table or technology to answer this question.
