A rental agent claims that the mean monthly rent, H, for apartments on the east side of town is less than $650. A random sample of 12 monthly rents for apartments on the east side has a mean of $646, with a standard deviation of $19. If we assume that the monthly rents for apartments on the east side are normally distributed, is there enough evidence to conclude, at the 0.1 level of significance, that he is less than $6507...
A rental agent claims that the mean monthly rent, H, for apartments on the east side of town is less than $675. A random sample of 16 monthly rents for apartments on the east side has a mean of $673, with a standard deviation of $19. If we assume that the monthly rents for apartments on the east side are normally distributed, is there enough evidence to conclude, at the 0.05 level of significance, that u is less than $675?...

Example 13: Use Chebyshev's theorem with X = 68, n = 85 and S = 10 and do questions a- (a) Calculate the percentage (p) of data points that is within k =3 standard deviations of the mean. Substitute the given value of k into Chebyshev's formula and evaluate p • Write p as a percentage to one decimal place. p88.9% (b) Find the number of standard deviation (k) on either side of the mean that cuts off p=75% of...
