A random variable X follows a Binomialdistribution with n=209 and p=0.65.Using the Normal approximation of theBinomial distribution, calculate thecontinuity corrected Z-score forobserving a number of successesgreater than or equal to 126. You donot have to estimate the probability.(Hint: the continuity correction is anadjustment included in the calculationto reflect that we are estimatingprobability for a discrete distributionwith a continuous distribution. Enteryour answer to two decimal places. Suppose that a test has a distributionthat is normal with a mean of 542.6and a standard deviation of 95.6.Calculate the exam score thatcorresponds to the 90th percentile.Enter your answer to the nearestinteger. Hint: The 90th percentile ofthe standard normal curve is z = 1.282.
