A report states that the mean yearly salary offer for students graduating with a degree in accounting is$48,722. Suppose that a random sample of 50 accounting graduates at a large university who received joboffers resulted in a mean offer of $49,870 and a standard deviation of $3900. Do the sample data providestrong support for the claim that the mean salary offer for accounting graduates of this university ishigher than the national average of $48,722?Ho: μ =Ha:α=Select an answerP-value =Based on the above we chooseQuestion Help: Post to foruSubmit Question(Put in the correct symbol and value)✓ Select an answerReject the null hypothesisFail to reject the null hypothesis

Research Question: Is there a difference between the average height of male and female basketball players in the club? 28 male and 25 female basketball players from the club were randomly selected. Use the following image to answer the questions below. Carry out an appropriate hypothesis test to answer the above Research Question. Q1) The null and alternative hypotheses are : Choose one from below -H0: μ = 0, H1: μ ≠ 0 -H0: μ = 170, H1: μ ≠ 170 -H0: μm- μf = 167.489, H1: μm- μf ≠ 167.489 -H0: μm- μf = 0, H1: μm- μf ≠ 0 H0: μm- μf = 170.27, H1: μm- μf ≠ 170.27 Q2) What is the assumption you need to make ? Choose one from below -The shape of the histogram indicates that the scores may be from a normal distribution and/or the sample size is reasonably large so the sample mean will be from a normal population -None of these -Since nπnπ and n(1−π)n(1−π) are both ≥5, the Central Limit Theorem applies and we can assume that p arises from a normal distribution -The boxplots…
Telephone Calls A researcher knew that before cell phones, a person made on average 2.5 calls per day. He believes that the number of calls made per day today is higher. He selects a random sample of 34 individuals who use a cell phone and asks them to keep track of the number of calls that they made on a certain day. The mean was 2.6. At a=0.01, is there enough evidence to support the researcher's claim? The standard deviation for the population found by a previous study is 0.6. Assume that the variable is normally distributed. Use the critical value method with tables.

mline Assume that, on the average, normal rhesus monkeys spend an mean of 60 minutes dreaming while sleeping at night (thus, u 60 minutes). Time spent dreaming is E typically referred to as REM sleep (Rapid Eye Movement). You are interested in the effects a new dream-enhancing drug has on dreaming since an increase in the time spent dreaming while sleeping is thought to be a good thing in terms of getting a "restful" sleep. You want to pursue testing the drug in humans if there is any evidence that it significantly increases nightly dreaming time in these nonhuman primates. Ten rhesus monkeys are administered the drug in the morning and their dream time (in minutes) is monitored that night. The alternate hypothesis is: the drug will increase time spent dreaming, or the time in REM sleep. You obtain the following times (minutes) each monkey spent dreaming: 52, 69, 74, 60, 67, 65, 69, 55, 63, 68 Set alpha at a- .01, and complete step 4 of the hypothesis testing procedure, what decision…

Fomulate a Two independent means test hypothesis question.
In the twentieth century, it was a common practice in Southern California for houses to be built with pools in the backyard. For new homes, however, that practice may be changing, possibly as a measure to help reduce climate change. A recent study examined a random sample of 171 houses built in Southern California in the twentieth century and an independent, random sample of 75 new houses built in Southern California. The sample of twentieth century houses contained 76 houses with pools, and the sample of new houses contained 30 houses with pools. Based on this survey, can we conclude, at the 0.01 level of significance, that the proportion p, of all Southern California twentieth century houses that were built with pools is greater than the proportion p, of all new Southern California houses that were built with pools? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the…
