An automobile dealer conducted a test to determine whether the time needed to complete a minor engine tune-up depends on whether a computerized engine analyzer or an electronic analyzer is used. because tune-up time varies among compact, intermediate, and full-sized cars, the three types of cars were used as blocks in the experiment. the data (time in minutes) obtained follow.
car
compact intermediate full size
analyzer computerized 50 55 63
electronic 42 44 46
the following regression model can be used to analyze the data for a randomized block design involving two treatments and three blocks.
e(y) = 0 + 1 x 1 + 2 x 2 + 3 x 3
a) show the values of the variables below. if your answer is "zero" enter "0".
analyzer x 1
computerized ?
electronic 1
car x 2 x 3
compact 0 0
intermediate 1 ?
full size 0 ?
enter negative values as negative number.
show the estimated regression equation (to 1 decimal, if necessary).
y = + x 1 + x 2 + x 3
what is the value of the t test statistic for the type of analyzer (to 2 decimals)? use α = .05 to test for any significant differences.
what is the p-value?
what is your conclusion?

Which equation represents a circle with a center at (–3, –5) and a radius of 6 units? (x – 3)2 + (y – 5)2 = 6 (x – 3)2 + (y – 5)2 = 36 (x + 3)2 + (y + 5)2 = 6 (x + 3)2 + (y + 5)2 = 36

Ialready asked this but i never got an answer. will give a high rating and perhaps brainliest. choose the linear inequality that describes the graph. the gray area represents the shaded region. y ≤ –4x – 2 y > –4x – 2 y ≥ –4x – 2 y < 4x – 2

Suppose that prices of a gallon of milk at various stores in one town have a mean of $3.71 with a standard deviation of $0.10. using chebyshev's theorem, what is the minimum percentage of stores that sell a gallon of milk for between $3.41 and $4.01? round your answer to one decimal place.
