The scores on the Wechsler Adult Intelligence Scale are approximately Normal, with ?=100μ=100 and ?=15σ=15 . If you scored 130130, your score would be higher than approximately what percent of adults?

ACT scores overall have a mean of 1017 and s = 207. If a college wants to admit only the top 30% of those, what score would they use as the minimum required? (Round to the appropriate whole number score). They would admit scores of and above.

The scores on the Wechsler Adult Intelligence Scale are approximately Normal, with ?=100 and ?=15 . The score needed to be among the highest 10% of all scores is closest to:

If a person’s z-score equalas 2.08, what is their percentile? Thank you.

There are two national college-entrance examinations, the scholastic aptitude test (SAT) and the American College Testing program (ACT).  Scores on the SATs are approximately normal with mean 500 and standard deviation 100.  Scores on the ACTs are approximately normal with mean 18 and standard deviation 6. Use the links provided for the Normal  (Links to an external site.)calculator and the Inverse Normal  (Links to an external site.) calculator to help complete the problems, you do not need to do any work out by hand. (instructions on how to use these calculators can be found in the week 5 star on the home page)  a)  What percent of all SAT scores are above 600? b)  Which is the greater accomplishment, scoring 630 on the SAT or 22 on the ACT ? Explain your reasoning for your choice. c)  How high a score in the SAT is needed to place in the top 2.5%.

In California, we need more rain to sustain the health of our natural environment, argriculture, and economic. A group of statistics students in Oxnard College recorded the amount of rain during 2016-2017 school year, measuring the intensity by the inches of rain, and the results were: Inches of Rain 1 2 3 4 5 6 Frequency 1 2 8 2 1 1 The mean (¯xx¯) rain intensity:  inches (Please show your answer to 1 decimal place.)The median rain intensity:  inchesThe mode rain intensity:  inches (Please separate your answers by ',' in the bimodal situation. Enter DNE if there is no mode or if there are more than two modes.)

If we multiply the data values by a constant (say, c), how this will affect the geometric mean? Use the equation in image to prove it, and give an example.
