a data set has a mean of 68 and standard deviation of 6. An element in this set is 51. What is z-score for 51? Round your answer

gogolik [260]

z = -2.83

<u>Explanation:</u>

Given:

Mean, μ = 68

Standard deviation, σ = 6

Data point, x = 51

Z score, z = ?

We know:

$z = \frac{data point - mean}{standard deviation} \\\\z = \frac{x - u}{p}$

Substituting the value we get:

$z = \frac{51-68}{6} \\\\z = -2.83$

A negative z score says that the data point is below average.

A shop sells chocolate, vanilla and strawberry ice cream cones. In one day, 45% of the ice cream cones sold are vanilla and 17%

True [87]

Answer:

950

Step-by-step explanation:

As, 45% will be vanilla, and 17% will be strawberry

So chocolate will be = 38%

As, 45%+17%+38% = 100%

So 38% of 2,500 = chocolate cones

= 38/100 x 2,500 = 950

So the number chocolate ice cream cone sold is 950.
