Answer:

D.2

Step-by-step explanation:

The z-score of an appliance that stopped working at 64 months is 2

What is z score?

Standard score or z score in statistics is defined as the number of standard deviations by which that the value of a score is above or below the mean value.

The formula to find the z score of a data is,

z = (x - μ) / σ

Here x is the observed value, μ is the mean and σ is the standard deviation.

Given that,

Mean = 48 months

Standard deviation = 8 months

x = 64 months

Substituting in the formula,

z = (64 - 48) / 8 = 2

Hence the z score of the appliance is 2.

11. One term, about 700 Statistics 2 students at the University of California, Berkeley, were asked how many college mathematics courses they had taken, other than Statistics 2. The average number of courses was about 1.1; the SD was about 1.5. Would the histogram for the data look like (i), (ii), or (iii)? Why?

Answers

Answer:

(i)

Step-by-step explanation:

Given that the mean value of the distribution is 1.1, then we can safely assume that the peak value will be reside around one with a variability measure, standard (1.5) represents changes in distribution away from the mean value. The could be to either side of the distribution. However, the cannot be a negative value for the number of courses taken, hence, the maximum value we can have to the left is 0. (figures to the far left of the distribution are negative). This means that the curve will fall towards the right, (positive direction hence giving a right skewed distribution.
