Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the Z score to determine the proportion. It will be much quicker than waiting for one of us to answer. (2)
To determine the p-value associated with a given value of the standardized test statistic z, you need to refer to a standard normal distribution table or use statistical software.
In this case, a z-score of 1.05 corresponds to the area under the standard normal curve to the right of 1.05. Since it is a one-tail test, we are interested in the area to the right of 1.05.
Using a standard normal distribution table, you can find the area to the right of 1.05 by looking up the closest value to 1.05 in the table and using the corresponding area. Sometimes the table provides z-scores up to two decimal places, so you may need to estimate.
Based on the information given, the closest value to 1.05 in the standard normal distribution table is 1.05 itself. The corresponding area is approximately 0.3531.
Therefore, the correct answer is (1) 0.3531.
