I only need help with (e) and (f). Thanks!
Please show work by hand
Use R code:
y=c(63,54,69,50,72,45,60,40,56,31,40,45,25,23,28)
group=c("T1","T1","T1","T1","T1","T2","T2","T2","T2","T3","T3","T3","T3","T3","T3")
TukeyHSD(aov(y~group), conf.level=.95)
Output:
Tukey multiple comparisons of means
95% family-wise confidence level
Fit: aov(formula = y ~ group)

Can you give me code for R for question (a) and (d)? I have the plots but I do not know how the codes work. for (a) (d-1) (d-2) A study was conducted to explore the effects of ethanol on sleep time. Fifteen rats were randomized to one of three treatments. Treatment 1 got only water (conto). Treatment 2 got 1g of ethanol per kg of body weight, and treatment 3 got 2g/kg of ethanol. The amount of REM sleep...
A study explored the effect of ethanol on sleep time. Fifteen rats were randomized to one of three treatments. Treatment 1 was water (control). Treatment 2 was 1g of ethanol per kg of body weight, and Treatment 3 was 2g/kg. The amount of REM sleep (in minutes) in a 24hr period was recorded: Treatment 1 63 54 69 50 72 Treatment 2 45 60 40 56 Treatment 3 31 40 45 25 23 28 Are these data strong evidence REM...
i need help with this question, please show work by hand no excel, spss thank you ! Assume you're using an alpha of 05, and a two-tailed test, to make your decision about whether to reject the null hypothesis. Assume that 18 subjects received one of three treatments and produced the data reported in Data Set B. Conduct a one-way ANOVA to see if the means of the three treatments are different on a statistically significant level. Complete an ANOVA...
Please answer showing all the work by hand ie not using excel , minitab,... (For (a) please show all the work on how you got the values for the table) 2.) Suppose customer satisfaction tests are given to random samples of customers from five different restaurant chains. The samples are chosen so that each chain provides data from three major cities (Montreal, Ottawa, Toronto). Perform an analysis using the data below, treating the city as blocks. Restaurant 52 79 (a)...

Please do question by hand (not in R). Show enough work for me to understand. Thanks. 4. August, Hung, and Houck (1974) studied collagen metabolism in children deficient in growth hormone before and after growth hormone therapy. The data in Table 3.4 are the values of heat-insoluble hydroxyproline in the skin of children before and 3 months after growth hormone therapy. Can we conclude on the basis of these data that growth hormone therapy increases heat-Insoluble hydroxyproline in the skin?...
Please do work by hand (not in R) and show enough work so I can understand how to do it myself. Thanks. 1. The data in Table 3.3 are a subset of the data obtained by Kaneto, Kosaka, and Nakao (1967). The experiment investigated the effect of vagal nerve stimulation on insulin secretion. The subjects were mongrel dogs with varying body weights. Table 3.3 gives the amount of immunoreactive insulin in pancreatic venous plasma just before stimulation of the left...
I have this assignment that I need help with, I turned it in but I got a bad grade for it, could someone please help me take an overview of it or take a look at it. but I want to change the project to Fundraising for kids in need all over the world. Because there is an assignment that I did in the past that is connected to it. Develop a work breakdown structure (WBS) for the project. Break...
Need help, please show work 12 Preventative care refers to care taken to prevent future diseases rather than to treat current ones. Compared with ER care, preventative care is rarely urgent, and ben- efits can be difficult to measure: if you had the flu vaccine this year but did not catch the flu, i is impossible to tell if it was the shot or assiduous hand-washing that preserved you. a Given this description of preventative care, would you expect preventative...
