You are testing the claim that having lights on at night increases weight gain (abstract). A sample of 10mice lived in an environment with bright light on all of the time and 8 mice who lived in an environmentwith a normal light/dark cycle is given below. Test the claim using a 10% level of significance. Assume thepopulation variances are unequal and that the weight changes are normally distributed.

Husband and Wife Ages as Paired Data Exercise 2.213 introduces a dataset giving the ages of the two people getting married for a sample of 105 marriage licenses. All of the couples in the sample were male-female couples. We are interested in whether the sample provides evidence that husbands are, on average, older than their wives. Because this is paired data (with each husband paired with his wife), we answer this question by first finding the difference in ages (Husband’s age minus Wife’s age) for each couple. For the 105 differences, the mean difference is 2.829 years with a standard deviation of 4.995. Test to see if, when getting married, the average age of husbands is greater than the average age of wives. Show all details of the test. State the hypotheses. μdμd is the mean difference in ages of all male-female married couples. H0 : μd _____ 0 Ha : μd_______0 PLEASE ANSWER THIS QUESTION I NEED HELP Find test statistic and p-value.

Using the image attached please assist by:1. Using R-Studio code, carry out relevant tests to determine if the assumptions of normality and homogeneity of variance were violated. Discuss the findings and quote relevant statistics in your response and provide the necessary hypotheses. fyi: there is no need to present the associated output tables, the code used only would suffice. Just show workings that I may follow closley.
In a regression, p value of an effect is 0.001, less than the level of significance (alpha = 0.05). This means that (choose all that apply) o The effect is significant o Its coefficient is not zero o The effect can be ignored o Its coefficient is zero

John Fleming, chief administrator for a district hospital, is concemed about costs for tests In the hospital's lab. Fleming has asked you to evaluate costs for the past month. The following Information is avallable: a. Basically, two types of tests are performed in the lab-blood tests and smears. During the past month, 2,610 blood tests and 3,480 smears were performed in the lab. b. Small glass plates are used in both types of tests. During the past month, the hospital purchased 17.400 plates at a cost of $41,760 This cost is net of a 6% quantity discount. 1,740 of these plates were still on hand unused at the end of the month; there were no plates on hand at the beginning of the month. c. During the past month, 1,600 hours of labour time were recorded in the lab. The cost of this labour time was $19,440. d. Varlable overhead cost last month in the lab for utilities and supplies totalled $10,880. The hospital has never used standard costs. By searching industry literature, hoever, you…
A psychologist was interested in the effects of alcohol on mate selection at night clubs. Her prediction was that after alcohol had been consumed, subjective perceptions of the physical attractiveness of another person would become more "inaccurate" (a phenomenon known as the beer-goggles effect). She was also interested whether this effect was different for men and women. She selects a group of participants to join her at a night-club: 14 men and 14 women. She then randomly assigns each participant to either consume multiple alcoholic beverages (the 'alcohol group) or to consume no alcohol (the 'no-alcohol' group). At the end of the evening, she takes a photograph of the person each participant was chatting up. She then asked a pool of independent raters to assess the attractiveness of the person in each photo (higher scores indicating higher levels of attractiveness). Which of the following lists include all significant effects? Alcohol No alcohol 6.6 3.8 Men
