Suppose that the duration of a particular type of criminal trial is known to be normally distributed with a mean of 24 days and a standard deviation of 6 days. Part (a) In words, define the random variable X. the mean time of all trials the number of trials that last 24 days the length, in days, of a criminal trial the length, in hours, of a criminal trial Part (b) Give the distribution of X. X ~ , Part (c) If one of the trials is randomly chosen, find the probability that it lasted more than 27 days. (Round your answer to four decimal places.) Sketch the graph. WebAssign Plot WebAssign Plot WebAssign Plot WebAssign Plot Write the probability statement. P Part (d) 64% of all trials of this type are completed within how many days? (Round your answer to two decimal places.) days

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
