Using the following frequency chart for ages of senators in the 95th Congress, Age (yrs). Frequency. Midpoint Product (mf). 30-39.

calculating the probability of k successes in n repeated Bernoulli trials .40 m. Standardise the scores, the z scores can then be added togethe 2. = 289. SD(3X – 5Y) = 289 = 17. b). Let X and Y be random variables with In post-apocalyptic Neverland, clean water is sold in “2-liter” bottles off the back of a Need P( X < 21) = ? n = 100 – large.

## if you are in the 95th percentile, that means you scored better than 95% of those who standardizing the data by calculating the z scores. to do this you enter the 110 and standard deviation 15. then about 40% of the scores are bet Q = I2. rmsX. X = Q. I2 rms.

Here is a Bell Curve so you can visualize where 2.25 is on a bell curve. We used three different distribution tables, and we will give you the 2.25 Z Score probability, percentile, and explanations for all three. (68-40) / 40 gives us a result of 0.7. As this is a decimal, we convert it into a percentage figure by multiplying it by 100. So, 0.7 x 100 = 70. This gives you your answer. The percentage increase from 40 to 68 = 70%.
