Find z such that 59% of the standard normal curve lies between −z and z. (Round your answer to two decimal places.)

Z = 0.82

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean and standard deviation , the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Find z such that 59% of the standard normal curve lies between −z and z.

The normal distribution is symmetric, which means that this is:

From the 50 - (59/2) = 20.5th percentile

To the 50 + (59/2) = 79.5th percentile.

The 20.5th percentile is -Z and the 79.5th percentile is Z.

79.5th percentile

Z with a pvalue of 0.795.

Looking at the z-table, it is Z = 0.824.

Rounding to two decial places, the answer is Z = 0.82.

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
