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 large adjusted gross incomes. If a taxpayer claims larger th average itemized deductions for a given level of income, the chances of an IRS audit are increased. Data (in thousands of dollars) on adjusted gross income and the average or reasonable amount of itemized deductions follow.

Several years ago, the Arcadia school system was criticized because the average Arcadia High School graduate could read at only the ninth-grade level. After this report was made, a special reading program was established to upgrade skills. The AHS principal wants to know if the reading program worked. If it has, he will request that an accreditation team visit the school. If the program has not improved the reading level to at least 10.0 (sophomore level), the administrator would like to avoid the embarrassment of a poor review. To determine the average reading level of the senior class, we select ten seniors at random. We assume that reading scores are normally distributed. The reading scores for the ten seniors are shown in Table 1. Table 1: Reading Scores for Sample High School Seniors Student Reading Score 1 13.4 2 12.1 3 11.4 4 10.6 5 10.3 6 10.2 7 9.8 8 9.7 9 9.4 10 8.6 Calculate the sample mean…

The American Heart Association is about to conduct an anti-smoking campaign and wants to know the fraction of Americans over 38 who smoke. Step 1 of 2: Suppose a sample of 273 Americans over 38 is drawn. Of these people, 79 smoke. Using the data, estimate the proportion of Americans over 38 who smoke. Enter your answer as a fraction or a decimal number rounded to three decimal places. Step 2 of 2: Suppose a sample of 273 Americans over 38 is drawn. Of these people, 79 smoke. Using the data, construct the 85% confidence interval for the population proportion of Americans over 38 who smoke. Round your answers to three decimal places. Lower end point, upper end point
A researcher has conducted a study to investigate the relationship between how important a person thinks appearance is and how much they spend on clothes each month, The first variable was 'self- rating of the importance of appearance' measured on a ten point scale (where 1 = not important and 10 = extremely important). The second variable was 'amount of money spent on clothes each month' measured by asking people to estimate to the nearest five pounds how much they spent in a typical month, The results are in the table below: Participant Self-rating of Amount spent on of clothes month (Maloti) s (initials) importance each appearance HP 6 80 EP 8 120 SF 100 PR 110 MS 75 JP 36 AG 15 BF 50 (a) Describe how an appropriate descriptive statistic could be used with the data in this table.

A researcher gives a depression scale to 300 people now, 6 weeks later, and 6 months later. She finds that the depression scale means are relatively the same over those three time periods. Does this mean that the depression scale is valid, and/or reliable? Explain.
Can someone explain the formulas needed and what variables go where? 445 randomly selected bulbs were tested in a laboratory, 316 lasted more than 500 hours. Find a point estimate of the proportion of all bulbs that last more than 500 hours.
kindly recheck this because I posted it on my other account but I think the first answer is wrong, I trust you to recheck it properly.
Please help needed on this asap. Thanks so much! It has been observed that some persons who suffer colitis, again suffer colitis within one year of the first episode. This is due, in part, to damage from the first episode. The performance of a new drug designed to prevent a second episode is to be tested for its effectiveness in preventing a second episode. In order to do this two groups of people suffering a first episode are selected. There are 170 people in the first group and this group will be administered the new drug. There are 132 people in the second group and this group wil be administered a placebo. After one year, 14% of the first group has a second episode and 18% of the second group has a second episode. What is a 90% confidence interval for the difference in true proportion of the two groups.
Help me on number 3 only
A typical treatment for Acinetobacter baumannii infection, for example, is a regimen of ampicillin, consisting of 250 mg, 4 times a day for 1 week. But antibiotics are used for a variety of medical issues by many people in the United States. Based on this information, estimate the weight, in kilograms, of ALL antibiotics ingested by people in the US each year. State any other assumptions and show all of your work.
