- ($1,000s) ($1,000s) To the Internal Revenue Service (IRS), the reasonableness of total itemized deductions depends on the taxpayer's adjusted gross income. Large deductions, which include charity and medical deductions, are more reasonable for taxpayers with larg given level of income, the chances of an IRS audit are increased.

The average class score, measured as a percentage, is about 72.2; exactly 50% of the students are male; and the average of colgpa (grade point average at the start of the term) is about 2.81. score = 32.31 + 14.32 colgpa (2.00) (0.70) n = 856, R² = .329, R = .328. 29.66 + 3.83 male + 14.57 colgpa score = (2.04) (0.74) (0.69) n = 856, R? = .349, R = .348.If , n=70, mean = 3.586, S= 0.074, μ=3.5, t value is 9.7727 and df is 69, then find (a) Using p value of 0.05 and test the claim (using t table) then write your conclusion ?

- The manager of a resort hotel stated that the mean guest bill for a weekend is $600 or less. A member of the hotel's accounting staff noticed that the total charges for guest bills have been increasing in recent months. The accountant will use a sample of future weekend guest bills to test the manager's claim. (a) Which form of the hypotheses should be used to test the manager's claim? Explain. Ho: u 2 600 HaiH 600 Но: и 3D 600 Ha: u + 600 The hypotheses Ho: µ 2 600 and H: µ 600 should be used because the accountant wants to test the manager's claim that the mean guest bill u is less than or equal to 600 and find evidence to support u > 600. The hypotheses Ho: u = 600 and H: µ + 600 should be used because the accountant wants to test the manager's claim that the mean guest bill u is equal to 600 and find evidence to support u + 600. (b) What conclusion is appropriate when H. cannot be rejected? We are not able to conclude that the manager's claim is wrong. We cannot conclude that u >…Explain how does the null hypothesis test using a t ratio.Please do not rely too much on chatgpt, because its answer may be wrong.

- State the conditions for performing a Friedman test.“Statistics is concerned with understanding the real world through the information that wederive from classification and measurement. Its distinctive characteristics is that it deals withvariability and uncertainty which is everywhere”.ii. Read the Statement and identify which measurement of scale is used in statement withreasons?(a) Currently, many countries are suffering from COVID-19. Pakistan is also one ofthem. Many patients are in different conditions such as mild, moderate andsevere illness.(b) The time is continuously passing ahead of seconds, minutes and so on; and iswithout a zero point of time. (c) The entrepreneur conducts a survey with the employees to evaluate the degreeof agreement with the company policies. In this survey 60% of the totalemployees agree with the policies, 10% just agree with some policies, 10%remain neutral. 10% disagree and 10% totally disagree with rules and policies.Assume you perform a study to detect how using social networks affects people's hapiness level. You have 20 volunteers. Your study is planned as follows. All participants are known to be active users of social networks. First you ask every participant to fill in special questionary that allows you to estimate their hapiness level. After that all participants will avoid using of social networks for one week. After this week they complete similar questionary to detect their new level of hapiness. Then for each participants their new hapiness level is compared the initial one. Assume that for each participant their hapiness level is changed: either decreased or increased. Let X be the random variable that models the number of participants for who increased their happiness level. Let Xobs = 16, i.e. 16 out of 20 participants become more happy, and it's the only data you can make decision on. Your significance level is 5%.
- Both Questions Please!!Dave is driving on an American Interstate highway which has a speed limit of 55 mph. At 2 pm he is at milepost 110 and at 5 pm he is at milepost 290. Is this enough evidence to prove that Dave was speeding? Prove using the Mean Value Theorem.0. You have 10 identical cartons each holding 10 water bottles. All bottles weigh 10 oz. each, except for one defective carton in which each of the 10 hottles weighs on 9 oz. only. A scale is available for weighing. (a) Suggest a method for locating the defective carton. *(b) What is the smallest number of times the scale is used that guarantees finding the defective carton? (Hint: You will need to be creative in deciding what to weigh.)
