A butcher at a certain store has the scales calibrated for accuracy. The scales must measure a standardized 3-pound weight at exactly 3 pounds with accuracy within 0.018 pound. (a) Write the possible measured scale weights (in Ib) using plus/minus notation. Ib ± Ib (b) Write the possible measured scale weights (in Ib) using interval notation. (Simplify your answer completely.) Ib (c) All of the measured scale weights must be between which two values (in Ib)? All of the measured scale weights must be between a lower value of Ib and an upper value of Ib.

If  p = 0.78, then q  is equal to ?

Chi-square may be uses with a. Nominal data b. Interval data C. Ratio data d. Ordinal data e. All of the options

The mean daily maximum temperatures at Komakuk Beach, in the Yukon, were recorded for The month from 1958 to 1990. The data are represented by the formula T=17.11sin(0.60M – 21.83)– 5.38, where Tis the temperature ("C) and Mis the number of the month in the year (1 to 12). a) What is the maximum mean daily temperature? b) What is the minimum mean daily temperature? c) What is the mean daily temperature for May? d) In a typical year, during how many months will the mean daily temperatures be higher than 0°C? Give your answer to the nearest tenth of a month.
