Use R. Provide Solution and R Code within each
problem.
A study was conducted to determine the average weight of newborn
babies. The distribution of the weight of newborn babies has a
standard deviation of σ = 1.25lbs. A random sample of 100 newborn
babies was taken and weights measured. The mean weight of the
babies in the sample was 7.3 lbs.
a. Construct a 95% confidence interval for the true mean weight
of newborn babies.
b. Interpret the confidence interval...

ANSWER USING R CODE
Using the dataset 'LakeHuron' which is a built in R dataset
describing the level in feet of Lake Huron from 1872- 1972. To
assign the values into an ordinary vector,x, we can do the
following 'x <- as.vector(LakeHuron)'. From there, we can access
the data easily. Assume the values in X are a random sample from a
normal population with distribution X. Also assume the X has an
unknown mean and unknown standard deviation. With this...

I need this in R code please: Use the dataset ’juul’ in package
’ISwR’ to answer the question. (1) Conduct one-way ANOVA test to
test if the mean of igf1 of each level of tanner are the same? (2)
What is the mean of igf1 in each level of tanner? (3) If there is
any difference, which ones appear to be different? (Use pairwise t
test for each pair of level with bonferroni method)
