show works please
29. A large data set has a maximum value of 87 and a minimum value of 47. Using only the range, what is the estimated sample standard deviation s? assume the distribution is mound shaped. Hint: See Empirical rule notes! 30. Find z.05 Recall that this means that 5% lies in the right tail. Look on t table! 31. The probability density function for a random variable is given by f(x)-x/8, (0Ex2). (Probability Area under the curve!) 32. A distribution has a mean of 110 and a standard deviation of 20 If nothing is known about the shape of the distribution, what is the minimum percentage of data between 60 and 160 Chebyshev)Explanation / Answer
29)
Solutions/Discussion:
The correct answer depends on your professor.
Some professors say to take the range divided by 4 while others would have you divide by 6, i.e.
s approx. equals
Range/4 = (87-47)/4 = 10
Range/6 = (87-47)/6 = 6.67
