General guidance

Concepts and reason
Normal distribution: Normal distribution is a continuous distribution of data that has the bell-shaped curve. The normally distributed random variable x has mean and standard deviation.
Also, the standard normal distribution represents a normal curve with mean 0 and standard deviation 1. Thus, the parameters involved in a normal distribution are mean and standard deviation.
Standardized z-score: The standardized z-score represents the number of standard deviations the data point is away from the mean.
• If the z-score takes positive value when it is above the mean (0).
• If the z-score takes negative value when it is below the mean (0).
Sampling distribution of sample mean:
The sampling distribution of the sample mean for the given sample size n consists of the collection of the means of all possible samples of size n from the population.

Fundamentals

Let , then the standard z-score is found using the formula given below:

Where X denotes the individual raw score, denotes the population mean, and denotes the population standard deviation.
The sampling distribution of the sample mean is,
Some of the formulas for finding probability are,

Procedure for finding the z-value is listed below:
1.From the table of standard normal distribution, locate the probability value.
2.Move left until the first column is reached.
3.Move upward until the top row is reached.
4.Locate the probability value, by the intersection of the row and column values gives the area to the left of z.

Step-by-step

Step 1 of 6

By using the central limit theorem the shape of the sampling distribution of is approximately normal with mean 86 and standard deviation is 2.

Use the central limit theorem to identify the distribution of the sampling distribution.

Step 3 of 6
