Answer :

Z-score, also called standard score, is the amount of standard deviations a data point is from the mean of a data set.To find the Z-score for which the area to the right is 0.05, we can use a Z-score table or calculator. The correct option is A) 1.64.


The standard normal distribution is a normal distribution with a mean of zero and a standard deviation of one. The Z-score is the number of standard deviations a data point is from the mean of a data set. It can be calculated using the formula:

Z = (X - μ) / σ

where X is the data point, μ is the mean of the data set, and σ is the standard deviation of the data set.

In this question, we are given that the area to the right is 0.05.

This means that the area to the left is 0.95.

We can use a Z-score table or calculator to find the Z-score that corresponds to an area of 0.95.

The Z-score table gives us the area to the left of a Z-score, so we need to look for the area closest to 0.95.

Using the Z-score table, we find that the Z-score that corresponds to an area of 0.9505 is 1.64.

This means that a data point with a Z-score of 1.64 is 1.64 standard deviations above the mean of the data set.

Therefore, the correct option is A) 1.64.
