Aradio station in myrtle beach announced that at least 90% of the hotels and motels would be full for the memorial day weekend. the station advised listeners to make reservations in advance if they planned to be in the resort over the weekend. on saturday night a sample of 58 hotels and motels showed 49 with a no-vacancy sign and 9 with vacancies. what is your reaction to the radio station’s claim after seeing the sample evidence? use a = .05 in making the statistical test. what is the p-value? anderson, david r.. essentials of statistics for business and economics (p. 434). south-western college pub. kindle edition.

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) without doing any computations, order the data sets according to increasing value of standard deviations. (i), (iii), (ii) (ii), (i), (iii) (iii), (i), (ii) (iii), (ii), (i) (i), (ii), (iii) (ii), (iii), (i) (b) why do you expect the difference in standard deviations between data sets (i) and (ii) to be greater than the difference in standard deviations between data sets (ii) and (iii)? hint: consider how much the data in the respective sets differ from the mean. the data change between data sets (i) and (ii) increased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference îł(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). none of the above
