claim that the rate of inaccurate orders is equal to 10%. Does the accuracy rate appear to be acceptable?

Answers

Answer 1

A normal distribution with a mean of zero and a standard deviation of one is known as the standard normal distribution. yes it is acceptable

Explain about the Standard normal distribution?

One type of the normal distribution is the standard normal distribution. It happens when a typical random variable's mean and standard deviation are both one. In other terms, the term "standard normal distribution" refers to a normal distribution with a mean of 0 and a standard deviation of 1.

The mean, median, and mode of a normal distribution are all equal and it is symmetric, unimodal, and asymptotic. Perfect symmetry surrounds the center of a normal distribution. To put it another way, the left and right halves of the center are mirrored.

The standard normal distribution is centered at zero, and the standard deviation indicates how much a specific measurement deviates from the mean.

n = 381

Number of orders that were not exact as a percentage = 40/318 =0.125

= P - P/√p(1 - p)/n

= 0.125 - 0.10/√0.10(0.90)/381

= 0.025/√0.09/381

=0.025/0.048

=0.52
