(a) What is the probability a randomly selected student in the city will read more than 93 words per minute? The probability is 0.3446. (Round to four decimal places as needed.) Interpret this probability. Select the correct choice below and fill in the answer box within your choice. O A. If 100 different students were chosen from this population, we would expect to read less than 93 words per minute. O B. If 100 different students were chosen from this population, we would expect to read exactly 93 words per minute. O C.

High school students across the nation compete in a financial capability challenge each year by taking a National Financial Capability Challenge Exam. Students who score in the top 13 percent are recognized publicly for their achievement by the Department of the Treasury. Assuming a normal distribution, how many standard deviations above the mean does a student have to score to be publicly recognized? (Round your answer to 2 decimal places.)
estion Help In a psychology journal, researchers reported that a chief executive officer's facial structure can be used to predict a firm's financial performance. The study involved measuring the facial width-to-height ratio (WHR) for each in a sample of 51 CEOS at publicly traded Fortune 500 firms. These WHR values (determined by computer analyzing a photo of the CEO's face) had a mean of x = 1.81 and a standard deviation of s = 0.12. Use this information to complete parts a and b below. a. Find and interpret a 90% confidence interval for u, the mean facial WHR for all CEOS at publicly traded Fortune 500 firms. (Round to three decimal places as needed.) O A. The 90% confidence interval for mean facial WHR indicates that the true mean facial WHR for the CEOS in the sample is between and with 90% confidence. O B. The 90% confidence interval for mean facial WHR indicates that 90% of all CEOS at publicly traded Fortune 500 firms have a WHR between and O C. The 90% confidence interval for…

Cardiovascular Disease, Pulmonary Disease The duration of cigarette smoking has been linked to many diseases, including lung cancer and various forms of heart disease. Suppose we know that among men ages 30-34 who have ever smoked, the mean number of years they smoked is 12.7 with a standard deviation of 5.2 years. For women in this age group, the mean number of years they smoked is 9.4 with a standard deviation of 3.1. (Assume that number of years spent smoking can be measured exactly and no continuity correction is necessary. Round your answers to four decimal places.) USE SALT (a) Assuming that the duration of smoking is normally distributed, what proportion of men in this age group have smoked for more than 21 years?

When we describe our data, we list three basic properties of the frequency distribution. One of them is the shape of the distribution. The other two are: the independent and dependent variables a measure of central tendency and a measure of variability the variance and the standard deviation whether it is normal or skewed
