3. Solve the following by hand, and by using either R or SAS: Let μ1-H2,H3 be, respectively, the means of three normal distributions with a common but unknown variance σ2. In order to test, at the 0-: 0.05 significance level, the hypothesis Ha : μι μ2 against all possible alternative hypotheses, we take an independent random sample of size 4 from each of these distributions. Determine whether...

6. This problem considers the simple linear regression model, that is, a model with a single covariate r that has a linear relationship with a response y. This simple linear regression model is y = Bo + Bix +, where Bo and Bi are unknown constants, and a random error has normal distribution with mean 0 and unknown variance o' The covariate a is often controlled by data analyst and measured with negligible error, while y is a random variable....

IGNORE (i)
(ii) The procedure of finding series solutions to a homogeneous
linear second-order ODEs could be accurately described as the
“method of undetermined series coefficients”.
(iii) The underlying idea behind the method of undetermined
coefficients is a conjecture about the form of a particular
solution that is motivated by the right-hand side of the equation.
The method of undetermined coefficients is limited to second-order
linear ODEs with constant coefficients and the right-hand side of
the ODE cannot be an...

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...
