Manufacturing and product development a a typical washing machine has several different cycles, including soak, wash, and rinse. the energy consumption of a washing machine is linked to the length of each cycle. a random sample of 21 washing machines was obtained, and the length (in minutes) of each wash cycle was recorded. the summary statistics are x 37.8 and cycle times is normal. a. find a 90% confidence interval for the true mean wash cycle time. write a solution trail for this problem

The construction of copying qpr is started below. the next step is to set the width of the compass to the length of ab. how does this step ensure that a new angle will be congruent to the original angle? by using compass take the measures of angle and draw the same arc according to it.

Given are five observations for two variables, x and y. xi 1 2 3 4 5 yi 3 7 5 11 14 which of the following is a scatter diagrams accurately represents the data? what does the scatter diagram developed in part (a) indicate about the relationship between the two variables? try to approximate the relationship betwen x and y by drawing a straight line through the data. which of the following is a scatter diagrams accurately represents the data? develop the estimated regression equation by computing the values of b 0 and b 1 using equations (14.6) and (14.7) (to 1 decimal). = + x use the estimated regression equation to predict the value of y when x = 4 (to 1 decimal). =
