1. 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 (control). Treatment 2 got lg of ethanol per kg of body weight, and treatment 3 got 2g/kg of ethanol. The amount of REM sleep in a 24hr period was recorded, in minutes. Data are below: Treatment 1: 63,...

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...

1. A dairy scientist is testing a new feed additive. She chooses 13 cows at random from a large population of cows. She randomly assigns mold 8 to get the old dict, and nnew-5 to get the new diet including the additive. The cows are housed in 13 separated pens and each gets separate...

Hi,
Could someone please give detail explanation of the following
graphs. I try to understand what assumptions are being violate here
ie (constant variance, independent residuals, linearity) sample
size is n=270 observation. I think the variance in top left graph
is not constant; there is huge gap in middle of data, but i do not
know how to explain formally,
I really looking for someone who has a strong understanding of
statistics to provide justification. I want to understand if...

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...

Solve d,e and f please using R code
Part I: qqplots This part deals with qqplots of all kinds. Let's do some easy expe riments, first. Let's take a sample from a normal distribution with mu-2, sigma 3, and then look at the hist and the qqplot of that data: set.seed(3) n 100 # Sample size x norm(n,2,3) # Sample from N(mu-2, sigma-3) hist(x) # Looks normal. But that depends on breaks. qqnorm(x) # This doesn't depend on binsize, and...

I have couple questions for this Problem;
1- can you show me on the graph how to solve and identify the

13-10. An article in Environment International [1992, Vol. 18(4)] described an experiment in which the amount of radon released in showers was investigated. Radon-enriched water was used in the experiment, and six different orifice diameters were tested in shower heads. The data from the experiment are shown in...

A scientist wants to see if the type of four vitamin supplements (A, B, C, D) affects the weight gain (y in grams) of laboratory animals. The experiment was conducted in a completely randomized design with five separately caged animals for each treatment. Since the caloric intake (in calories/10) will differ among animals and influence y, she...
