Assume that r 2 equals. 50 for the relationship between heights and weight for adults. Indicate whether the following statements are true or false. Fifty percent of the variability in heights can be explained by variability in weights. There is a cause-effect relationship between height and weights. The heights of 50 percent of adults can predicted exactly from their weights. Fifty percent of the variability in weights is predictable from heights.

A correlation tests whether differences exist between two variables. Question 1 options: a) True b) False Question 2 (1 point) You have tested to find whether a relationship exists between hours of sleep the night before an exam and grade on the exam. You have a participant pool of n = 30, df = 28. Your hypothesis is that a significant relationship will exist, where those with more hours of sleep receive higher grades on the exam. This is a...

True or false?: 1) If the relationship between 2 variables is perfect the standard error of estimate equals 0. 2) F=-1.0 is never possible in ANOVA. 3) If F<1.0 in an ANOVA we don’t even have to bother to look at F critical values table since the result cannot be significant. 4) In an ANOVA, sample size n1=10, n2=12, n3=30, and n4=100, we can use Tukey’s HSD to conduct multiple comparisons.

~~~~~~~~~~~~TO BE COMPLETED USING RSTUDIO~~~~~~~~~~~~~~ ~~~~~~~~~~~~(Please display all RCode used)~~~~~~~~~~~~~~ Regression Is there a relationship between the number of stories a building has and its height? Some statisticians compiled data on a set of n = 60 buildings reported in the World Almanac. You will use the data set to decide whether height (in feet) can be predicted from the number of stories. (a) Load the data from buildings.txt. (Note that this is a text file, so use the appropriate...

2) Suppose the weight of a newborn baby follows a normal distribution with a mean of 3500 grams and a standard deviation of 600 grams. a. What is the probability that the weight of a randomly selected newborn exceeds 4000g? b. For a random sample of 36 newborns, what is the probability that their mean weight is less than 3450g? 3) Suppose that 5% of American adults are vegetarian. Find the probability that in a random sample of 500 American...
