Suppose you want to compare the average calories in popular pies from United States, Great Britain, and Scotland. Complete the following one way ANOVA test used to determine if there is any evidence to suggest the mean calories in the popular regional pies is not the same for the three countries. Assume the regional pies’ calories follows a Normal distribution and use the 5% level of significance. United States: 300, 270, 290 Great Britain: 400, 338, 525, 280 Scotland: 350, 426, 215 Leave answers as whole number and round any answer to 2 decimals where applicable.

The figure shows a 3.5-kg block that sits on a horizontal surface. The friction between the block and the surface can be neglected. Another 2.0-kg block is deposited on top of the 3.5-kg block. The static coefficient of friction between the two blocks is μs = 0.20. The kinetic coefficient of friction between them is μk = 0.10. What is the magnitude of the largest horizontal force that can be applied to the bottom block such that the top block moves with the bottom block without slipping?
