Scientists conducting a study on global climate change want to determine if there has been an increase in the number of days per year that the temperature in El Paso rises above 100 degrees Fahrenheit. In 1981, there were 21 days where the temperature roseabove 100 degrees Fahrenheit. The scientists want to know whether the average number of days per year that the temperature rises above 100 degrees Fahrenheit has increased.Which hypothesis test would be most appropriate for this study?O One mean (sigma known) - one sample zO One mean (sigma unknown) - one sample tO Mean of differences, using dependent samples (paired data)O Difference of two means (independent samples)O Several means (ANOVA)O One proportionO Difference of two proportionsO Chi-Squared test for independence

Do You Have a Fever? Sometimes when you are sick, your forehead feels really warm. You might have fever. How can you find out whether you do? By taking your temperature , of course. But what temperature should the thermometer show if you're healthy? Is this temperature the same for everyone? Several years ago, researchers conducted a study to determine whether the "accepted" value for normal body temperature, 98.6oF, is accurate. They used an oral thermometer to measure the temperatures of a random sample of healthy men and women aged 18 to 40. As is often the case, the researchers did not provide their original data. Allen Shoemaker, from Calvin College, produced a data set with the same properties as the original temperature readings. His data set consists of one oral temperature reading for each of the 130 randomly chosen, healthy 18- to 40-year-olds. A dotplot of Shoemaker's temperature data is shown below. A vertical line at 98.6oF was added for reference. Statcrunch Data Link…
A professor using an open-source introductory statistics book predicts that 60% of the students will purchase a hard copy of the book, 25% will print it out from the web, and 15% will read it online. She has 200 students this semester. Assuming that the professor's predictions were correct, calculate the expected number of students who read the book online.
