If n = 420 and ˆpp^ (p-hat) = 0.7, construct a 90% confidence interval. Give your answers to three decimal

What value should go in the overlap of the two circles? (that's where the 'X' is). Explain your reasoning

I have a dataset from 600 preschoolers with measures of grip strength for each individual. One individual subject had a z score of -1.5. Approximately how many preschoolers would have a grip strength lower than this individual. Show work please I don't understand

Among 157 Cuban American men ,the mean systolic blood pressure was 146 mm Hg with a standard deviation of 27. We wish to know if based on these data, we may conclude that the mean systolic blood pressure for a population of Cuban American is greater than 140. Use α=0.01 (solve without excel) , show work

What percent of the distribution lies within one standard deviation of the mean? Within two standard deviations of the mean? Within three standard deviations of the mean? You can type your answer with equations/formulas for this question.

Calculate the test statistic. (X^2)Enter your answer rounded to three decimal places.

Ginny’s professors conspired to all give a test on the same day. She gets an 82 on her psychology exam with μ = 76 and σ = 12. She receives a z-score of -.25 on her management exam. Finally, she scored at the 50th percentile on her normally distributed math exam. Place her test scores in order from lowest to highest score.

for data set of the pulse rates for a sample of adult females the lowest pulse rate is 36 bpm the mean of the list of pulse rate is X bar equals 72 bpm and their standard deviation is 12.9 bpm. what is the difference between the pulse rate of 36 bpm and the meatballs rid of the females how many celebrations is that the difference found in part a convert the pulse rate of 36 bpm to a z score if we consider pulse rates that convert to a Z score between -2 and 2 to be neither significantly lower significantly high is the pulse rate of 36bpm significant

Solve using the z score table P(xs 5) O = 3 Z = X-u_ Fill in the graph to represent the desired shaded area and standard deviation line.
