Suppose a chef claims that her meatball weight is less than 4 ounces, on average. several of her customers do not believe her, so the chef decides to do a hypothesis test, at a 10% significance level, to persuade them. she cooks 14 meatballs. the mean weight of the sample meatballs is 3.7 ounces. the chef knows from experience that the standard deviation for her meatball weight is 0.5 ounces. h0: μ=4; ha: μ< 4 α=0.1 (significance level) what is the test statistic (z-score) of this one-mean hypothesis test, rounded to two decimal places? provide your answer below:

You are remodeling your kitchen. you’ve contacted two tiling companies who gladly told you how long it took their workers to tile of a similar size jim completed half the floor in 8 hours. pete completed half of the other floor in 7 hours. if pete can lay 20 more tiles per hour than jim, at what rate can jim lay tiles
