you will see that the area that corresponds to the z score 1.09 is 0.3621. Since the results are different, you may be tempted to think that you’re not doing things right or that you’re looking at the wrong table. This isn’t either. The reality is ...
The Z-value of 165 cm is -0.5Using the Z-table or programming we can find that the p-value for the two z-values:The probability of a z-value smaller than -0.5 (shorter than 165 cm) is 30.85% The probability of a z-value smaller than -1.5 (shorter than 155 cm) is 6.68%...
A standard normal table, also called the unit normal table or Z-table, is a table for the values of Φ calculated mathematically, and these are the values from the cumulative normal distribution function. A standard normal distribution table is used to find the probability that a statistic is ...
The TableYou can also use the table below. The table shows the area from 0 to Z.Instead of one LONG table, we have put the "0.1"s running down, then the "0.01"s running along. (Example of how to use is below)Z0.000.010.020.030.040.050.060.070.080.09 0.0 0.0000 0.0040 0.0080 ...

The standard score (more commonly referred to as a z-score) is a very useful statistic because it (a) allows us to calculate the probability of a score occurring within our normal distribution and (b) enables us to compare two scores that are from different normal distributions. The ...
From the table (see above), we find that P(Z < -1.20) = 0.1151; and P(Z < -1.40) = 0.0808. Therefore, P(-1.40 < Z < -1.20) = P(Z < -1.20) - P(Z < -1.40) = 0.1151 - 0.0808 = 0.0343.In school or on the Advanced Placement Statistics Exam, you may be called upon ...
