Answer: (1,5,7,10,11,15)

To get the union of two sets of numbers, all you do is combine the numbers from least to greatest. If a number repeats in the 2 sets, you only put it once.

Answer:

M ∪ N = (1, 5, 7, 10, 11, 15)

Step-by-step explanation:

A set is said to be a union of two sets A and B which has the elements present in the set A and B or in both. Union of two sets A and B will be denoted by A ∪ B.

For the two given sets M = (1, 7, 10, 11, 15) and N=(5, 15), their union M ∪ N will contain all the elements from the two sets but none of the elements will be repeated.

Therefore, M ∪ N = (1, 5, 7, 10, 11, 15)

<h3>What is a sample size?</h3>

The sample size is a term used in market research for defining the number of subjects included in a sample size. By sample size, we understand a group of subjects that are selected from the general population and is considered a representative of the real population for that specific study.

Empirical rule states that for a normal distribution, 68% of the values are within one standard deviation from the mean, 95% of the values are within two standard deviation from the mean and 99.7% of the values are within three standard deviation from the mean.

For a population mean of 20.15 and a standard deviation of 3.7

68% are within μ ± σ/√n,

hence,

68% = 20.15 ± 3.7/√20 = (19.32, 20.98)

For a sample size of 20 players, 68% of the sample means fall within 19.32 and 20.98.
