Question

Use the standard normal (z score) table to find: P(-1.00 ≤ z)

Find the probability that a data value picked at random from a normal population will have a standard score (z) that lies between the following pairs of z-values. z = 0 to z = 2.10

Answer #1

From normal distribution table

**P(-1.00 ≤ z)=0.15866**

Solution2:

he probability that a data value picked at random from a normal population will have a standard score (z) that lies between the following pairs of z-values. z = 0 to z = 2.10

P(Z<2.10)-P(Z<0)

From normal distribution table

=0.9821-0.500

=0.4821

**The probability that a data value picked at random from
a normal population will have a standard score (z) that lies
between the following pairs of z-values. z = 0 to z = 2.10 is
0.4821**

16. Use a table of cumulative areas under the normal curve to
find the z-score that corresponds to the given cumulative area. If
the area is not in the table, use the entry closest to the area.
If the area is halfway between two entries, use thez-score
halfway between the corresponding z-scores. If convenient, use
technology to find the z-score.

use the standard normal distribution table to determine the
missing values of the following probability. P(0≤Z≤?)=0.4884

Use the standard normal table to find the z-score that
corresponds to the cumulative area 0.7454. If the area is not in
the table, use the entry closest to the area. If the area is
halfway between two entries, use the z-score halfway between the
corresponding z-scores.
