Is it possible for the standard deviation of a dataset to be larger than its variance? Explain mathematically. Give an example to explain the above statement.
You know that buffaloes have adult weights that are distributed by B = N(2000,200) where the given mean and standard deviation is in Ibs. You inherit a baby buffalo. Find the probability that your buffalo grows up to be at least 1990 pounds. Find the probability that your buffalo will eventually weigh between 1950 and 2100 lbs. How much would your buffalo have to weigh in order to outweigh 98% of all grown buffalo.
Suppose that the random variable X represents the length of a punched part in centimeters. Let Y be the length of the part in millimeters. If E(X) = 4 and V(X) = 0.25, what are the mean and variance of Y? Mean = i mm Variance = mm²
The time spent waiting in the line is approximately normally distributed. The mean waiting time is 4 minutes and the variance of the waiting time is 9. Find the probability that a person will wait for less than 7 minutes. Round your answer to four decimal places.
The time spent waiting in the line is approximately normally distributed. The mean waiting time is 4 minutes and the variance of the waiting time is 1. Find the probability that a person will wait for more than 5 minutes. Round your answer to four decimal places.
A homeowner has installed a new energy-efficient furnace. It is estimated that over a year the new furnace will reduce energy costs by an amount that can be regarded as a random variable with a mean of $200 and a standard deviation of $60. Stating any assumptions you need to make, find the mean and standard deviation of the total energy cost reductions over a period of 5 years.
Find the variance if X~N(0, 7) and 95% of the data are between -7 and 7.

your task is to search three (3) real life examples or application of normal distribution. Explain each of them by providing reasons about its importance.
A medical researcher claims that the variance of the heart rates (in beats per minute) of smokers is greater than the variance of heart rates of people who do not smoke. Samples from two groups are selected and the data is given below. Using = 0.05, test whether there is enough evidence to support the claim. Smokers Non Smokers m = 25 n = 18 s = 36 s = 10
