The expected value of the discrete distribution is of 20.97, hence option C gives the correct answer.

<h3>What is the mean of a discrete distribution?</h3>

The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability.</u>

Hence, according to the table, the expected value is given by:

E(X) = 12 x 0.08 + 18 x 0.15 + 20 x 0.31 + 22 x 0.08 + 24 x 0.15 + 25 x 0.23 = 20.97.

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). Six times Jason
Helga [31]
Based on the given above, collection of books of Nathan and Jason can be translated into the following equations:
6J + 1/3N = 134
1/3 J + N = 31; J = Jasons and N=Nathan
Solving two equations with two unknowns simultaneously,
Jason = 21 books and Nathan = 24 books

iren2701 [21]

Answer:

μ = 1.3468

Step-by-step explanation:

Given data:

Observations

0.85

0.88

0.88

1.06

1.09

1.12

1.29

1.31

1.42

1.49

1.59

1.62

1.65

1.71

1.76

1.83

sum of the observations = 21.55

now,

the total number of the given data, n = 16

now, the mean is given as:

Mean = (Sum of all the observation) / (Total number of observations)

on substituting the values in the above formula, we get

Mean = 21.55 / 16

or

Mean = 1.3468

Since, it is given that the data follows normal distribution.

thus, the normal mean can be used as the point of estimator (μ)

i.e μ = 1.3468
