 Given that X is a binomial random variable with very large n, the binomial probability P(X = 5) is ... Given that X is a binomial random variable with very large n, the binomial probability P(X = 5) is approximated by the area under a normal curve between  a. 5 and 5  b. 4 and 6  c. 4.5 and 5.5  d. None of these choices.Q. 2In performing a regression analysis which of the following must be true about the distribution of the error variable?  a. The distribution is normal with mean zero.  b. The errors associated with one y value are independent of errors associated with another y value.  c. The standard deviation is constant for each value of x.  d. All of these choices are true.Q. 3In general, the binomial probability P(X  x) is approximated by the area under the normal curve to the left of x - .5.   Indicate whether the statement is true or falseQ. 4In simple linear regression, the coefficient of correlation r and the least squares estimate b1 of the population slope 1:  a. must be equal.  b. must have the same sign.  c. are not related.  d. None of these choices.Q. 5In general, the binomial probability P(X  x) is approximated by the area under the normal curve to the left of x + .5.   Indicate whether the statement is true or false Read 33 times 2 Replies
