Suppose X ~ N (2, 3). What value of x has a z-score of -0.69? Suppose X ~ N(4, 2). What value of x is two standard deviations to the right of the mean? I need help solving these two problems. If you could explain that would help understand the steps of solving these types of problems. Thank you for your time
When I need to determine which standard deviation would give the better grade, what if the z-score is negative such as -.8 and -.4. Wouldn't the .-4 score provide a better grade because it's closer to m=42? The oridinga score is 38 and the mean is 42 but there are two standard deviation scores of 5 (answer was -.8) and 10 (answer was -.4) and I need to decide which one give the better grade.
Hugo averages 41 words per minute on a typing test with a standard deviation of 7.5 words per minute. Suppose Hugo's words per minute on a typing test are normally distributed. Let X = the number of words per minute on a typing test. Then, X - N(41, 7.5). Suppose Hugo types 45 words per minute in a typing test on Wednesday. The z-score when x = 45 is x = 45 is This z-score tells you that standard deviations to the (right/left) of the mean, Correctly fill in the blanks in the statement above. Select the correct answer below: Suppose Hugo types 45 words per minute in a typing test on Wednesday. The z-score when x = 45 is -0.533. This z-score tells you that x = 45 is 0.533 standard deviations to the left of the mean, 41. Suppose Hugo types 45 words per minute in a typing test on Wednesday. The z-score when x = 45 is -0.381. This z-score tells you that x = 45 is 0.381 standard deviations to the left of the mean, 41. Suppose Hugo types 45 words per minute in a typing test on Wednesday. The…

A standardized exam’s score are normally distributed. In a recent year, the mean test score was 1477 and the standard was 315. The test scores of four students selected at random 1860 1230, 2160, and 1360. Find the Z- score that correspond to each value and determine wether any of the values are unusual. The Z-score for 1860 is-The Z-score for 1230 is-The Z-score for 2160 is-The Z-score for 1360is-
In a random sample of ten cell phones, the mean full retail price was $554.00 and the standard deviation was $167.00. Assume the population is normally distributed and use the t-distribution to find the margin of error and construct a 95% confidence interval for the population mean u. Interpret the results. Identify the margin of error. (Round to one decimal place as needed.)

In one math class, the first exam had an average score of 81.2% with a standard deviation of 10.9%. The second exam had a mean score of 79.3%, with a standard deviation of 19.9%. Based on these numbers, tell whether each statement is true or false. 1. There were probably some students that took a zero on Exam 1. The statement is ▼(Choose one(True/False)). 2. Most students did better on the second exam. The statement is ▼(Choose one(True/False)).
