Which of the following statements is not true? a) the standard deviation of the sampling distribution of sample mean = σ/√n b) the larger the sample size, the better will be the normal approximation to the sampling distribution of sample mean. c) the mean of the sampling distribution of sample mean is always the same as that of x, the distribution from which the sample is taken. d) the sampling distribution of the sample mean is always reasonably like the distribution of x, the distribution from which the sample is taken. e) the sampling distribution of sample mean is approximately normal, mound-shaped, and symmetric for n > 30 or n = 30.

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.

instead of subtracting you add the -6/8 and -1/8

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
