I have used z table to find z values.
P in the image stands for probability.
Hope this helps you !!!

Question 3 According to a study done by UCB students, the height for Martian adult males is normally distributed with an average of 65 inches and a standard deviation of 2.4 inches. Suppose one Martian adult male is randomly chosen. Let X-height of the individual. Round all answers to 4 decimal places where possible. a. What is the distribution of X? X-N b. Find the probability that the person is between 60.7 and 64.7 inches. C. The middle 20% of...

According to a study done by UCB students, the height for Martian adult males is normally distributed with an average of 66 inches and a standard deviation of 2.5 inches. Suppose one Martian adult male is randomly chosen. Let X = height of the individual. Round all answers to 4 decimal places where appropriate. a. What is the distribution of X? X ~ N(,) b. Find the probability that the person is between 63.5 and 69 inches. c. The middle...
(2)Heights of adult males are normal distributed with a mean of 65 inches and a standard deviation of 2 inches: a) Find the probability that randomly chosen male will have a height between 61 and 68 inches. b) Suppose you are the curator of James Madison's house where the height of the door jams are 70 inches. What is the chance that a randomly selected male will have to duck through the doorway? c) You are designing a new building...
1. The distribution of heights of adult females: We assume that height is normally distributed with a population mean of 65 inches and a population standard deviation of 4 inches. 2. The distribution of heights of adult males: We assume that height is normally distributed with a population mean of 70 inches and a population standard deviation of 5 inches. a. Above what Z-score value does 2.5% of the normal distribution fall? Using the formula for Z-scores and the Z-score...
7. Let X be the random variable denoting the height of a randomly chosen adult individ- ual. If the individual is male, then X has a normal distribution with mean of = 70 inches with standard deviation of σ| 3.5 inches: while if the individual is female. then X has a normal distribution with mean μ0-66 inches and standard deviation of ơ0 3 inches. |Note: For computing probabilities and quantiles for the normal distribution, use the R functions pnorm, dnorm,...

A sample of 10 adult men gave the following data on their heights and weights. Height (inches) X 62 62 63 65 66 67 68 68 70 72 Weight (pounds) Y 120 140 130 150 142 130 135 175 149 168 a. Generate the scatter plot of this data and graph the regression line in your plot. Include a picture of this graph and explain your impression of how well the line fits the data. b. State the equation of...
For the following data:, Avg. Height of Parents Male Offspring Height 55 57 58 60 59 63 60 63 62 65 68 68 70 74 70 73 71 75 72 76 73 77 Make scatter diagram of points showing the relationship between Avg Height of Parents (x-axis) and Male Offspring Height (y-axis). A positive slope would suggest a positive correlation of these measures. Give a quantitative genetic...
