I believe that cars with more mileage are worth less money. I decide to run a statistical analysis at the a = 0.01 significance level to testmy claim. From a large website specializing in selling used cars, I sample 6 used 2012 sedans at random. For each sedan, I recordIts mileage and the price that the car is listed at Data are as follows:Mileage14572083100744305043036500108940Price391011550101009170153409070Assume that responses follow the modelPrice = Bo - BiIMileage) + EWhere the error terms e satisfy the standard regression assumptionsCompute the correlation between price and mileage. (Round answers to 4 decimal points)a.Correlation: b.Which of the following is NOT an assumption made on the standard regression assumptions?O They all have the same standard deviationO They all have mean (expected value) OO They are all independent of each otherO They all follow a binomial distributionWhich of the following is true about the regression line?O The regression line minimizes the MSE of forecast errorsO The regression line is the line with the largest prediction accuracy.O The regression line minimizes the sum of the squares of the residuals.O Regression may only be performed if the standard regression assumptions hold.O All of the above.d.Is the slope of the regression line positive or negative?O PositiveO NegativeO NeitherO There is not enough information to tell.е.What is the null hypothesis for your hypothesis test?O Ho: Bo>0O Ho: Bo <0O Ho: Bo = 0O Ho: Bo #0O Ho: B1>0O Ho: B1<0O Ho: B1= 0O Ho: B1#0

Independent random samples of 27 people living on the west side of a city and 26 people living on the east side of a city were taken to determine if the income levels of west side residents are less than the income levels of east side residents. Given the testing statistics below, determine if the data provides sufficient evidence to conclude that the income levels of west side residents are less than the income levels of east side residents, at the 4% significance level
The respiratory disturbance index (RDI), which is the number of apneic and hypopneic episodes per hour of sleep, was used as a measure of severity of sleep apnea. An RDI of 5 or more indicates sleep-related breathing disturbances. The RDIs for the females and males samples in a study in US are as follows. At the 1% significance level, do the data provide sufficient evidence to conclude that the female patients are less suffer than male from the apnea disease?
A researcher looks at the mean salaries of male and female electricians and decides based on the evidence that there is no difference between the two groups. Given that there was a failure to reject the null hypothesis, it is possible that a type II error was made. Given the type of error made in this situation, what could researchers do to reduce the risk of this error? Choose a .01 significance level, instead of a .05 significance level. Increase the sample size.
According to the Center for Disease Control website, in 2011 at least 18% of high school students have smoked a cigarette. An Introduction to Statistics class in Davies County, KY conducted a hypothesis test at the local high school (a medium-sized–approximately 1,200 students–small city demographic) to determine if the local high school’s percentage was lower. One hundred fifty students were chosen at random and surveyed. Of the 150 students surveyed, 82 have smoked. Use a significance level of 0.05 and using appropriate statistical evidence, conduct a hypothesis test, and state the conclusions. Solve the following problems using the steps in conducting hypothesis tests.

For the conclusion, please use the following template. If you reject the null writeSince p-value is [write the value of your p-value] and is less than [write the value of alpha inpercent] we reject the null hypothesis at…
For a statistics class project, a college student randomly samples 75 men who exercise at a gym regularly and 68 women who exercise at a gym regularly. The college student records the number of minutes each person exercises in a given week. The college student believes that the mean number of minutes per week is lower for men than for women. The college student conducts a hypothesis test at the 5% significance level. What conclusion can you draw from the output? The data provide sufficient evidence to reject the null hypothesis and to conclude that the mean number of minutes exercised per week is lower for men than for women. The data provide sufficient evidence to conclude that there is no difference in the mean number of minutes exercised per week for men and women. The data do not provide sufficient evidence to conclude that the mean number of minutes exercised per week is lower for men than for women. We accept the null hypothesis, and conclude that there is a difference in…
Comfort Food Magazine states the average calories of a medium size hot dog is 209. The number of calories for a medium size hot dog is normally distributed. A random sample of 15 different brands of medium size hot dogs resulted in the following calorie count provided below. Can it be concluded that the average calories of a medium size hot dog will be 209 based on level significance of 0.01?
A researcher was interested in comparing the resting pulse rates of people who exercise regularly and of those who do not exercise regularly. Independent simple random samples of 16 people who do not exercise regularly and 12 people who exerciseregularly were selected, and the resting pulse rates (in beats per minute) were recorded. The summary statistics are as follows. Use a 0.025 significance level to test the claim that the mean resting pulse rate of people who do not exercise regularly is larger than the mean resting pulse rate of people who exercise regularly. a)Identify the null hypothesis, alternative hypothesis. b)Find the test statistics c)Find the critical value d)Conclusion about the null hypothesis e)State the conclusion
What source of variation is found in an ANOVA summary table for a within subjects design that is not in an ANOVA summary table for a between subjects design. What happens to this source of variation in a between-subjects design?
A Gallup poll to survey the top concerns of Americans was conducted. Suppose that 577577 women and 496496 men were independently and randomly selected, and that 283283 women and 186186 men chose the state of the economy as their biggest concern. Can we conclude that the proportion of women ( p1p1 ), choosing the state of the economy as their biggest concern, exceeds the proportion of men ( p2p2 )? Use a significance level of α=0.05α=0.05 for the test. Step 4 of 6 : Compute the value of the test statistic. Round your answer to two decimal places.
