I need help with all three parts. Thank you! Describe the sampling distribution of p̂ . Assume the size of the population is 25,000. n = 700, p = 0.594 Describe the shape of the sampling distribution of p̂ . Choose the correct answer below. A. The shape of the sampling distribution of p̂ is approximately normal because n≤0.05N and np(1−p)≥10. B. The shape of the sampling distribution of p̂ is approximately normal because n≤0.05N and np(1−p)<10. C. The shape...
compute p(x) using the binomial probability formula. then determine whether the normal distribution can be used to estimate this probability. if so, p(x) using the normal distribution and compare the result with the exact probability. n=78, p= 0.83, and x=60 for n= 78, p= 0.83, and x=60, find P(x) using the binomial probability distribution. P(x) _. (round to four decimal places as needed.) can the normal distribution be used to approximate this probability? A. no, the normal distribution cannot be...
A random sample of 40 binomial trials resulted in 16 successes. Test the claim that the population proportion of successes does not equal 0.50. Use a level of significance of 0.05. (a) Can a normal distribution be used for the p̂ distribution? Explain. Yes, np and nq are both less than 5.No, np is greater than 5, but nq is less than 5. No, nq is greater than 5, but np is less than 5.Yes, np and nq are both greater...
