Why is it that the formula to tell that the sampling distribution of p hat will be approximately normal is np must be greater than or equal to 10 and n(1-p) is greater than or equal to 10? Why is it 10? Why not 20 or other numbers? What is the reason behind 10? Thanks! ShapeLet ô be the sample proportion of successes in a random sample of size nselected from a population with proportion of successes p. Then, thesampling distribution of ô will be approximately normal whennp ≥ 10 and n(1 − p) ≥ 10For our example about students with driver's licenses, n = 50 and p = 0.3:np = 50(0.3) = 15 ≥ 10 andn(1 − p) = 50(1 – 0.3) = 35 ≥ 10-Therefore the distribution of p is approximately normal in this context.

Sol:- The rule of thumb that np ≥ 10 and n(1-p) ≥ 10 is based on the central limit theorem (CLT),…

suppose that a random sample of size 20 is taken from a normal distribution with unknown mean and known variance is equal to 1 and me is found to be 10 and normal distribution was used to as a prayer for the mean and it was found that the posterior maine was 15 and posterior standard aviation was 0.1 what is the mean and standard deviation for prior
A personality test has a subsection designed to assess the "honesty" of the test-taker. Suppose that you're interested in the mean score, μ, on this subsection among the general population. You decide that you'll use the mean of a random sample of scores on this subsection to estimate μ. What is the minimum sample size needed in order for you to be 90% confident that your estimate is within 3 of μ? Use the value 23 for the population standard deviation of scores on this subsection. Carry your intermediate computations to at least three decimal places. Write your answer as a whole number (and make sure that it is the minimum whole number that satisfies the requirements).
Which one of the following statements is false? 1 The standard deviation of the sampling distribution for a proportion will get smaller as the sample size gets bigger. 2 A probability can never be negative. 3 If a person tosses a fair coin 10 times and the first 9 tosses land on “heads,” there is a 50% chance the 10th toss will also land on “heads.” 4 If a person tosses a fair coin 10 times and the coin lands “tails” all 10 times, the chance it will land “heads” on the 11th toss will be greater than 50%.
Hello, I am having troubles with Example 1 in the elementary statistics book in Chapter 5.4 A sampling Distribution oF sample means: The number of times 4 people go grocery shopping in a month is given by the population values {1,3,5,7}. You randomly choose two of the four people, with replacement. List all possible samples of size n=2 and caclculate the mean of each. These means form the sampling distribution of the sample means. Find the mean, variance, and standard deviation of the sample means. Compare your results with the mean = 4, variance = 5, and standard deviation = 2.2. I know how they obtained the mean but using the formula to get variance I am not sure how they go 5/2 = 2.5. Thank you.

Suppose Jack and Diane are each attempting to use a simulation to describe the sampling distribution from a population that is skewed right with mean 60 and standard deviation 5. Jack obtains 1000 random samples of size n=5 from the population, finds the mean of the means, and determines the standard deviation of the means. Diane does the same simulation, but obtains 1000 random samples of size n=30 from the population What do you expect the mean of Jack's distribution to be? What do you expect the mean of Diane's distribution to be?
Suppose it is reported that 75 % of people subscribe to a I cable or satellite television service. You decide to test this claim by randomly sampling 131 people and asking them if they subscribe to cable or satellite televsion. (Round your answer to 4 decimals when necessary) Is the distribution of the sample proportion normal? Yes, the distribution of sample proportions is normal since np(1 − p) ≥ 10 O No, the distribution of sample proportions is not normal since np(1 − p) < 10 What is the mean of the distribution of the sample proportion? H₂² op = 0.75 What is the standard deviation of the distribution of the sample proportion? X 0.0551 X
Suppose that the mean value of interpupillary distance (the distance between the pupils of the left and right eyes) for adult males is 65 mm and that the population standard deviation is 5 mm. (Round your answers to four decimal places.) If the distribution of interpupillary distance is normal and a random sample of n = 25 adult males is to be selected, what is the probability that the sample mean distance x for these 25 will be between 63 and 67 mm? What is the probability that the sample mean distance x for these 25 will be at least 68 mm? Suppose that a sample of 100 adult males is to be obtained. Without assuming that interpupillary distance is normally distributed, what is the approximate probability that the sample mean distance will be between 63 and 67 mm? Without assuming that interpupillary distance is normally distributed, what is the approximate probability that the sample mean distance will be at least 68 mm?
