R can be used to find the critical value for an F distribution for a given significance level. For example, tofind the critical value (the value above which you would reject the null hypothesis) for a = 0.05 withd fbetween = 5 and dfwithin 60, then F1-0.05 is found with:-qf (1-0.05, df1-5, df2=60)Enter this code into RStudio to confirm you obtain the value 2.368.You conduct a one-way ANOVA with 7 groups and 10 subjects in each group (a balanced design). UseRStudio to find the critical values for a = 0.10 and a = 0.02 (report accurate to 3 decimal places).F₁- -0.10 =F1-0.02 =

A financial analyst of Woolworths is interested in the average number of months that it takes customers to pay off their account debt. He claims that the average number of months it takes is less than four. He takes a sample of fifty customers and records the number of months it takes each customer to pay off his debt. Suppose that the test statistic value to test this claim is calculated as -0.34, determine the p-value.
A study was conducted to examine the difference between the average cholesterol levels in the blood of men and females. It can be assumed that cholesterol levels follow a normal distribution in both populations and that the distribution in the populations is similar (e. Assume that cholesterol levels follow a normal distribution in both populations with similar variances). An equal number of measurements were made on men and women. The results were entered into R and the R code and output can be seen below: t.test(kol$mael-kol$kyn,var.equal = T) %3D Two Sample t-test data: kol$mael by kol$kyn t = 5.7731, df = 18, p-value alternative hypothesis: true difference in means is not equal to 0 95 percent confidence interval: 15.28775 32.78050 = 0.000018 sample estimates: mean in group Men mean in group women 219.2115 195.1774 1.

Two separate samples are selected from the same population. Each have an n=8. Both samples receive a different treatment. After the treatment, the first sample has SS=16 and the second sample has SS=24. With a mean of 3 for the first group and mean of 6 for the second group, compute the t statistic. State the conclusion of these findings.
It is known that in a certain town 30% of the people own an Kpfone. A researcher asks people at random whether they own an Kpfone. The random variable X represents the number of people asked up to and including the first person who owns an Kpfone. Determine that P(X <6).
The manager of the city pool has scheduled extra lifeguards to be on staff for Saturdays. However, he suspects that Fridays may be more popular than the other weekdays as well. If so, he will hire extra lifeguards for Fridays, too. In order to test his theory that the daily number of swimmers varies on weekdays, he records the number of swimmers each day for the first week of summer. Test the manager’s theory at the 0.01 level of significance.
