From the following list, single out those measurements for which the square root of a typical measurement is a proper estimate of the standard deviation of the distribution from which the measurement is drawn: (a) A 1-min count from a detector (b) A 5-min count from a detector ( c) The net counts from a detector over a 1-min period after background subtraction. (d) The counting rate expressed as counts per second based on a 100-s measurement (e) The average of five sequential 1-min counts (f) The sum of five sequential 1-min counts

# 3. The following code draws a sample of size $n=30$ from a chi-square distribution with 15 degrees of freedom, and then puts $B=200$ bootstrap samples into a matrix M. After that, the 'apply' function is used to calculate the median of each bootstrap sample, giving a bootstrap sample of 200 medians. "{r} set.seed (117888) data=rchisq(30,15) M=matrix(rep(0,30*200), byrow=T, ncol=30) for (i in 1:200 M[i,]=sample(data, 30, replace=T) bootstrapmedians=apply(M,1,median) (3a) Use the 'var' command to calculate the variance of the bootstrapped medians....

Using C++ Create a Blackjack program with the following features: Single player game against the dealer. Numbered cards count as the number they represent (example: 2 of any suit counts as 2) except the Aces which can count as either 1 or 11, at the discretion of the player holding the card. Face cards count as 10. Player starts with $500. Player places bet before being dealt a card in a new game. New game: Deal 2 cards to each...

A. Introduction and Objective Every test has at least two sources of variation that affect the results of the test. The first source of variation is due to the experimental procedure, such as using two different testing machines that have different calibrations, or different observers reading the same equipment differently. This type of variation is often called the experimental error The second source of variation is inherent in the specimens (or sample population) themselves. In other words, no two specimens...
