Though the two stores have beencomparable in the past, the owner has made several improvements to Store 2 and wishes to see if the improvements have made Store 2 more popular thanStore 1. Sales can vary considerably depending on the day of the week and the season of the year, so she decides to eliminate such effects by making sure torecord each store's sales on the same 8 days, chosen at random. She records the sales (in dollars) for each store on these days, as shown in the table below.DayStore 1Store 2144Hz1Explanation565Difference(Store 1 - Store 2)Send data to calculator V698Check23409 554362 604454069853216685450 801(a) State the null hypothesis Ho and the alternative hypothesis H₁.H:0Ho7O Search804840Based on these data, can the owner conclude, at the 0.05 level of significance, that the mean daily sales of Store 2 exceeds that of Store 1?

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…

text Claire and George are tasked with decorating Easter eggs. The amount of eggs that Claire can decorate in an hour is a random variable with ?μ = 20 and ?σ = 2. The amount of eggs that George can decorate in an hour is a random variable with ?μ = 15 and ?σ = 5. Assume the amount of eggs Claire and George decorate are independent of each other. (Round your answers to four decimal places, if needed.) (d) Claire decides to decorate Easter eggs for one hour today and for another hour tomorrow. What is the standard deviation of the total number of eggs she will decorate in total?Answer:
