You may need to use the appropriate appendix table or technology to answer this question. Advertisers contract with internet service providers and search engines to place ads on websites. They pay a fee based on the number of potential customers who click on their ad. Unforțunately, click fraud-the practice of someone clicking on an ad solely for the purpose of driving up advertising revenue–has become a problem. Businessweek reports that 4C percent of advertisers claim they have been a victim of click fraud. Suppose a simple random sample of 390 advertisers will be taken to learn more about how they are affected by this practice. (Round your answers to four decimal places.) (a) What is the probability that the sample proportion will be within ±0.04 of the population proportion experiencing click fraud? (b) What is the probability that the sample proportion will be greater than 0.45?

Diabetes is a serious disease that can affect anyone and requires lifelong monitoring. It is estimated that 422 million people worldwide are diabetic, a number four times higher than that registered 40 years ago, according to the World Health Organization (WHO). The fasting blood glucose reference values are: >Normal fasting glucose: less than 99 mg / dL;>Altered fasting glucose: between 100 mg / dL and 125 mg / dL;>Diabetes: equal to or greater than 126 mg / dL;>Low fasting glycemia or hypoglycemia: equal to or less than 70 mg / dL. Assuming that a study was carried out with 120 patients, the mean fasting blood glucose found, by UV-Vis spectrophotometry, was 88 mg / dL, the standard deviation was 30 mg / dL, which is the fraction (%) of patients who have pre-diabetes, blood glucose between 100 and 125 mg / dL?
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.

This problem is based on information taken from The Merck Manual (a reference manual used in most medical and nursing schools). Hypertension is defined as a blood pressure reading over 140 mm Hg systolic and/or over 90 mm Hg diastolic. Hypertension, if not corrected, can cause long-term health problems. In the college-age population (18-24 years), about 9.2% have hypertension. Suppose that a blood donor program is taking place in a college dormitory this week (final exams week). Before each student gives blood, the nurse takes a blood pressure reading. Of 190 donors, it is found that 26 have hypertension. Do these data indicate that the population proportion of students with hypertension during final exams week is higher than 9.2%? Use a 5% level of significance. Find the P-value of the test statistic. (Round your answer to four decimal places.) ANSWER IS NOT 2.711

Are cigarettes bad for people? Cigarette smoking involves tar, carbon monoxide, and nicotine (measured in milligrams). The first two are definitely not good for a person's health, and the last ingredient can cause addiction.

“Radon: The Problem No One Wants to Face” is the title of an article appearing in Consumer Reports. Radon is a gas emitted from the ground that can collect in houses and buildings. At certain levels, it can cause lung cancer. Radon concentrations are measured in picocuries per liter (pCi/L). A radon level of 4 pCi/L is considered “acceptable.” Radon levels in a house vary from week to week. In one house, a sample of 8 weeks had the following readings for radon level (in pCi/L): 1.9 | 2.8 | 5.7 | 4.2 | 1.9 | 8.6 | 3.9 | 7.2 a) Find the mean, median, and mode. b) Find the sample standard deviation, coefficient of variation, and range. c) Interpretation: Based on the data, would you recommend radon mitigation in this house? Explain.
