Suppose x has a distribution with a mean of 70 and a standard deviation of 52. Random samples of size n = 64 are drawn.(a) Describe the x distribution and compute the mean and standard deviation of the distribution.x has --Select-.+ distribution with mean u,and standard deviation o, =(b) Find the z value corresponding to x = 57.(c) Find P(x < 57). (Round your answer to four decimal places.)P(X < 57) =(d) Would it be unusual for a random sample of size 64 from the x distribution to have a sample mean less than 57? Explain.No, it would not be unusual because more than 5% of all such samples have means less than 57.No, it would not be unusual because less than 5% of all such samples have means less than 57.Yes, it would be unusual because more than 5% of all such samples have means less than 57.Yes, it would be unusual because less than 5% of all such samples have means less than 57.

Today, the waves are crashing onto the beach every 4.9 seconds. The times from when a person arrives at the shoreline until a crashing wave is observed follows a Uniform distribution from 0 to 4.9 seconds. Round to 4 decimal places where possible. The mean of this distribution is The standard deviation is The probability that wave will crash onto the beach exactly 0.6 seconds after the person arrives is P(x = 0.6) =
The lengths of pregnancies in a small rural village are normally distributed with a mean of 267 days and a standard deviation of 15 days. Let X be the length of a randomly recorded pregnancy in the village. What is the distribution of X? X ~ N (,) Please show the following answers to 4 decimal places. If a pregnancy randomly chosen in the village, find the probability that it lasted less than 244 days. If a pregnancy randomly chosen in the village, find the probability that it lasted between 290 and 298 days. Please show the following answer to a whole day. The 72nd percentile pregnancy length in this village is ___________ days.
A large group of students took a test in Physics and the final grades have a mean of 70 and a standard deviation of 10. The passing score is 60. The distribution is approximately normal. Using the 68-95-99.7 (empirical) rule, find the percentage of the students(a) scored between 60 and 80.(b) scored between 50 and 90.(c) higher than 80. (d) should pass the test.
Q1.[5 points]: A researcher wants to assess if there is a difference in the average age of onset of a certain disease for men and women who get the disease. Let µ = average age of onset for women and µ2 = average age of onset for men. A random sample of 30 women with the disease showed an average age of onset of 83 years, with a sample standard deviation of 11.5 years. A random sample of 20 men with the disease showed an average age of onset of 77 years, with a sample standard deviation of 4.5 years. Assume that ages at onset of this disease are normally distributed for each gender, and assume the population variances are equal. i. What are the appropriate null and alternative hypothesis? ii. What is the value of the test statistics? iii. Why you decided to use the test statistics in part ii ? For a significant level of 0.05, what is the critical value (or critical region)? What is the appropriate conclusion to this test? iv. V.
A population has a mean p= 160 and a standard deviation o=22. Find the mean and standard deviation of the sampling distribution of sample means with sample size n= 45. The mean is H- = |, and the standard deviation is o- = (Round to three decimal places as needed.)
7. If you made only n = 1 measurement of rack height, the standard deviation of 41 measurement would be (a) zero, because there is no difference between the value and the average. (b) Equal to the measured value. (c) Undetermined, because you need more measurements to find a standard deviation (d) Infinite because the denominator (n – 1) is zero.
Today, the waves are crashing onto the beach every 5.1 seconds. The times from when a person arrives at the shoreline until a crashing wave is observed follows a Uniform distribution from 0 to 5.1 seconds. Round to 4 decimal places where possible. The mean of this distribution is The standard deviation is The probability that wave will crash onto the beach exactly 1.4 seconds after the person arrives is P(x = 1.4) = The probability that the wave will crash onto the beach between 1.3 and 4.7 seconds after the person arrives is P(1.3 < x < 4.7) = The probability that it will take longer than 3.92 seconds for the wave to crash onto the beach after the person arrives is P(x > 3.92) = Suppose that the person has already been standing at the shoreline for 1.1 seconds without a wave crashing in. Find the probability that it will take between 2.4 and 3.8 seconds for the wave to crash onto the shoreline. 84% of the time a person will wait at least how long before the wave crashes in?…
