do online students perform differently than students in a traditional classroom? Las semester there was 100 students registered for the online version of a statistics course, and 100 Students registered for the traditional classroom version. All students took the smae final exam. Suppose the group of online students had a mean exam score of 75 with a standard deviaiton of 3. The group of classroom students had a mean exam score of 76 with a standard deviiton of 4. Do the sample data provide evidene that there is a difference in the average exam scores between the two groups? Test the relevant hypotheses at a significance level of a=0.05.
Please help me answer those with written solutions. Thanks a lot.

Perform a statistical analysis/test of hypothesis, showing all the steps in hypothesis testing. A business travel magazine wants to classify transatlantic gateway airports accordingto the mean rating for the population of business travelers. A rating scale with a lowscore of 0 and a high score of 10 will be used, and airports with a population meanrating greater than 7 will be designated as superior service airports. The magazine staffsurveyed a sample of 60 business travelers at each airport to obtain the ratings data. The sample for London’s Heathrow Airport provided a sample mean rating of 7.25 anda sample standard deviation of 1.052. Do the data indicate that Heathrow should bedesignated as a superior service airport?
You give all Stonehill students a measure of well-being (i.e. happiness) when they enter as first year students. You want to compare the average happiness scores for incoming first year students for the classes of 2021, 2022, 2023, and 2024. Which statistical test would you use to see if there are statistically significant differences of well-being (based on happiness scores) between the classes of 2021, 2022, 2023, and 2024? a. one sample t test b. two sample t test c. repeated measures t test d.

Read through this scenario and look at the data that was collected. State the null and all possible research hypotheses. Review the results below (I used SPSS) and answer the questions that follow. Scenario: A researcher wants to see if gender and / or income affects the total amount of help given to a stranger who is sitting on the side of a busy road with a sign asking for help. The independent variables are gender, income, and the interaction of gender and income. The dependent variable is total help. He wants to know if one or both factors – or the interaction of the two - affects the total amount of help offered. Because he is analyzing two independent variables (gender and income), he used a factorial ANOVA. His results show the main effect of each of the independent variables on the dependent variable (total help) and the interaction effect. The researcher is using a 95% confidence interval which means that he wants to be at least 95% sure that his independent variables…

Good credit: The Fair Isaac Corporation (FICO) credit score is used by banks and other lenders to determine whether someone is a good credit risk. Scores range from 300 to 850, with a score of 720 or more indicating that a person is a very good credit risk. An economist wants to determine whether the mean FICO score is more than the cutoff of 720. She finds that a random sample of 40 people had a mean FICO score of 760 with a standerd deviation of 95, Can the economist conclude that the mean FICO score is greater than 720? Use the a=0.01 level of significance and the P-value method with the T1-B4 Plus calculator. Part 1 of 4 State the appropriate null and altemate hypotheses.
