A scientific study was conducted to determine the hours of sleep that college students get per night. Thestudy surveyed 20 college students and obtained the following data:8.4, 8.4, 9.5, 7.2, 8.8, 7.4, 7.7, 8.4, 8.7, 7.5, 8.7, 8.6, 8.3, 7.7, 8.8, 8.1, 8.4, 8.6, 8.2, 7.5Assuming the population standard deviation is o = 0.71, construct a 98% confidence interval for theaverage hours of sleep per night that college students get.2ΖαMargin of Error: E =We are 98% confident that college students get an average of betweenhours andhours of sleep per night.

Spam: A researcher reported that 71.8% of all email sent in a recent month was spam. A system manager at a large corporation believes that the percentage at his company may be 77%. He examines a random sample of 500 emails received at an email server, and finds that 361 of the messages are spam. Can you conclude that the percentage of emails that are spam is less than 77% ? Use both a = 0.05 and a = 0.10 levels of significance and the P-value method with the TI-84 Plus calculator. Part: 0 / 5 Part 1 of 5 (a) State the appropriate null and alternate hypotheses.

evicard The use of both alcohol and tobacco by high school senibrs has declined in the last 30 years. Alcohol use is down from 68.2% to 43.1%, and the use of cigarettes by high school seniors has decreased from 36.7% to 20.4%. A random sample of 300 high school seniors from a large city indicated that 54 had smoked a cigarette during the 30 days prior to the survey. At the a = 0.05 level of significance is this lower than the national average?
The first test a doctor would order to determine whether a person is infected with HIV (the virus that causes AIDS) is the ELISA test. It detects antibodies and antigens for HIV. A study in Statistical Science by J. Gastwirth estimated that, if the person is actually infected with HIV, this test produces a positive result 97.7% of the time. If a person is not infected with HIV, the test result is negative 92.6% of the time. According the the US Centers for Disease Control (CDC), an estimated 1.1 million Americans out of a population of 321 million were infected with HIV in 2015. Using the information above, determine the probability that a randomly selected person whose ELISA test is positive actually is infected with HIV? a. What is the probability that a randomly selected American is infected with HIV? b. Using the answer to part (a) and the conditional probabilities of positive and negative ELISA test results, fill out the contingency table below: ELISA Test Result…
