which statement is the characteristic of the distribution that are not for the standard normal distribution?

Which statement is the characteristic of the t distribution that are not for the standard normal distribution? => The variance is greater than 1. or The mean, median and mode are equal to 0 and are located at the center of distributio..

Select the correct statement(s) on the standard normal distribution curve. I. The curve is sinusoidal (of the shape of sine curve). II. It is unimodal. III. The mean, median and mode are equal. IV. Area under the curve is assumed as 1. => II and IV only or II..

What percentage of area (approximately) under the normal distribution curve lies between a standard deviation of 1 and 2? => 15% or 13% or 27% or 30%..

Find the lowest control limit for a normally distributed curve with a mean of 15 and a standard deviation of 2.5. => 12.5 or 10 or 7.5 or 22.5..

The average price of a computer is $750. If prices of computers are approximately normally distributed with a standard deviation of $75, then what would be the maximum price of 10% of least-expensive computers? => $654 or $754 or $745 or $645..

The average price of a computer is $750. If prices of computers are approximately normally distributed with a standard deviation of $75, then what is the probability that a randomly selected computer costs more than $1000? => 3.3% or 0.33% or 0.04% or 0.4%..

The scores made by candidates in a certain test are normally distributed with mean 500 and standard deviation 100. What percentage of candidates received scores greater than 700? => 2.28% or 2.82% or 47.72% or 47.27%..

The scores made by candidates in a certain test are normally distributed with mean 500 and standard deviation 100. What percentage of candidates received scores which differ from 500 by more than 150 points? => 43.23% or 13.36% or 43.32% or 6.68%..

The average price of a bicycle is $300. The prices of the bicycles are normally distributed with a standard deviation of $60. What is the probability that a randomly selected bicycle costs more than $450? => 0.62% or 6.2% or 3.8% or 0.38%..

When can the normal distribution be used as an approximation to the binomial distribution? => n . p = 5, n . q = 5 or n . p ≤ 5, n . q ≤ 5 or n . p > 5, n . q < 5 or n . p ≥ 5, n . q ≥ 5..
