Answer:

11) mean=2 12) median=2 13)range =4

Step-by-step explanation:

11) the set is

0,0,1,1,1,2,2,2,2,2,3,3,3,4,4

so add all these which will give you 30 and then divide that by how many numbers are there in the set which there are 15, so 30 divided 15 =2

12) arrange numbers from smallest to largest and the number exactly in the middle is the median

wariber [46]

Answer:

E 0.923

Step-by-step explanation:

The Z score is a measurement used in statistics to determine the relationship between a value and a mean of a group of values measured as standard deviation from the mean. The z score (z) is given as:

$z=\frac{x-\mu}{\sigma}$ , Where μ is the mean, σ is the standard deviation and x is the value.

Given that:

σ = 7, μ = 80 and x = 90

$z=\frac{x-\mu}{\sigma}=\frac{90-80}{7} =1.43$

From the normal distribution table, P(X < 90) = P(z < 1.43) = 0.923
