The annual salary of teachers in a certain state X has a mean of μ = $54,000 and standard deviation of σ = $5,000. What is the probability that a randomly selected teacher from this state has an annual salary of $55,500 or more. Group of answer choices We can not solve this with the given information. 0.3821 0.0082

We can not solve this with the given information.

Step-by-step explanation:

Problems of normally distributed samples are solved using 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.

In this problem, we have that:

We have no information about wheter the distribution is normal or not, so we cannot solve the question.

The correct answer is:

We can not solve this with the given information.

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
