For a set of repeat measurements to be expected to be a normal random variable what conditions would have to met.
The some conditions of the normal random variable are as follows.
1) It is symmetric about mean value of the random variable. So that its mean, median and mode are equal.
2) It is follows empirical rule that is
i) 68% data of that random variable lies between one standard deviation from mean.
ii) i) 95% data of that random variable lies between t standard deviation from mean.
iii) i) 99.7% data of that random variable lies between three standard deviation from mean.

(5pt) During an experiment, you collect the following repeat measurements of some property in appropriate units: 13, 10, 11, 12, 12, 16, 17, 16, 18, 17, 16. Explain with full justification, including plots, whether this is a completely random set of measurements or it is subjected to some systemai influence. Would you calculate a precision limit from these data? (do not just give a yes, no, maybe - justify your answer). What would you do if you get such data?...
a. X is distributed as a Normal random variable, with a mean of 100 and a standard deviation of 20. You're considering taking a random sample of 1000 Xs, and calculating the sample mean Xbar. Of course, different random samples would give you different numbers. What is the standard deviation of all of the possible different Xbars you could have calculated? (Please report your answer to two decimal places, such as 5.67.) b. X is distributed as a Normal random...
Using R, code the following: The data set `normtemp` (**UsingR**) contains body measurements for 130 healthy, randomly selected individuals. The variable temperature contains normal body temperature data and the variable gender contains gender information, with male coded as 1 and female coded as 2. First, split the data by 'gender'. If the conditions for a two-sample t-test are met then perform the correct t-test to test if the population means (by gender) are equal. Make sure you run the correct...
The standard normal transformation, ?=?−?x/?x, transforms any normal random variable (?) to a standard normal random variable (?), which has a mean of 0 and a variance of 1. Consider a standard continuous uniform random variable (?), which is a continuous uniform random variable with a mean of 0 and a variance of 1. What is the equation for a standard continuous uniform transformation that transforms any ?~?(?,?) to ??
The age of a students in a class is a normal random variable. There are 80 students in our class. I select 9 students randomly and calculate the mean of their ages (sample mean). I repeat this experiment 1,000,000 times. Then I calculate the mean and standard deviation of the 1,000,000 sample means that I measured; the calculated values are 22 and 4, respectively. What is the probability that the age of a randomly selected student in the class is...
