Employers want to know which days of the week employees are absent in a five-day work week. Most employers would like to believe that employees are absentequally during the week. Suppose a random sample of 60 managers were askedon which day of the week they had the highest number of employee absences.The results were distributed as in the data below. For the population ofemployees, do the days for the highest number of absences occur with equalfrequencies during a five-day work week? Test at a 5% significance level.State the null hypothesis, the alternative hypothesis, the p value and whether youwill reject or not reject the hull hypothesis.Number of AbsencesExpected Number ofAbsencesMonday Tuesday Wednesday Thursday Friday151291512129121212

A sample of 30 students at a local college were given a test consisting of 10 questions about current news events. Thedistribution of the number of correct answers given is recorded in the frequency column of the table. Questions that were notanswered were marked incorrect. The frequency represents how many of the 30 students who took the test got a certain numberof answers correct. For example, three students answered five questions correctly. Determine this mean number of points x, earned on the test. Give your answer precise to one decimal place
A researcher is interested in the relationship between birth order and personality. A sample of n= 100 people is obtained, all of whom grew up in families as one of three children. Each person is given a personality test, and the researcher also records the person’s birth-order position (1st born, 2nd, or 3rd). The frequencies from this study are shown in the following table. On the basis of these data, can the researcher conclude that there is a significant relation between birth order and personality? Test at the .05 level of significance. Birth Position 1st 2nd 3rd Outgoing 13 31 16 Reserved 17 19 4 The expected frequencies for Outgoing, Birth Position 1st is: The expected frequencies for…

64 owners and a similar age group of pet owners. The pet owners are matched one to one with the non-pet owners for income, number of close friendships, and 0. A researcher uses a matched-subjects design to in- than singles without pets. A mood inventory survey vestigate whether single people with pets are happier happier is given to a group of 20- to 29-year-old non-p general health.

Test with a = .05 for two tails. b. Construct the 95% confidence interval to estimate the size of the mean difference in mood between the population of pet owners and the population of non-pet owners. (You should find that a mean difference of p, = 0 is an acceptable value, which is consistent with the conclusion from the hypoth- esis test.) %3D D. AB

A health educator wants to evaluate the effect of a dental film on the frequency with which children brush their teeth. Eight randomly chosen kids are measured on the number of times they brushed their teeth for one month before viewing the dental film and again for a month after the film.

Hint: Make sure you do After-Before. Step 1. Express the substantive question as two statistical hypotheses. H0: Answer Answer Answer H1: Answer Answer Answer Step 2. Draw the sampling distribution under the null hypothesis using the p < .05 as the criterion for statistical significance to determine the critical values. What is the center of the distribution?
