The Z score is a normal score with mean zero and the standard deviation one. The Z score value is located on the normal distribution curve and it is used to calculate the probability of the normal area curve.Answer and Explanation: The Z score is defined as: {eq}Z = \df...
Question: Use normal distribution to find the proportion of the normal curve that is at or above a z-score of 1.25. Z-score The standard normal probability distribution uses the Z-score to locate random values in the distribution. The Z-score is the numb...

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 ...

However, they found social media use/chatting to be associated with an increased probability of drinking, whereas computer gaming, especially on weekends, was associated with a decrease in probability of drinking. On the other hand, Coëffec et al. (2015) found alcohol use to be more common...
Age is a control variable as the propensity of parents to enroll their children in extracurricular tutoring class may fluctuate depending on the educational stage of the children. For example, as the child’s years of education increase and academic pressure continues to raise, the probability that...
Answer to: Use Z-table to find p-value, if the test value for the left sided test is found to be -2.15. - 0.9842 - 0.0158 - 0.0316 - 0.765 By...
A Z-score of 4 indicates that the stock is significantly overvalued compared with its historical mean. This could be a signal to short the stock, as it is expected to revert to its mean. Over the next few weeks, the initial excitement fades, and the stock price gradually fall back to ...
The t-distribution is a continuous probability distribution of the z-score when the estimated standard deviation is used in the denominator rather than the true standard deviation. The t-distribution, like the normal distribution, is bell-shaped and symmetric, but it has heavier tails, which means...
