**Flexural Strength of Concrete Beams**The following sample data provide the flexural strength (MPa) for concrete beams of a certain type. The values are as follows:7.3, 6.3, 6.8, 7.0, 7.6, 6.8, 7.0, 6.3, 7.9, 9.0, 7.8, 9.7, 7.8, 11.6, 11.8, 10.7**Objective:**Calculate a point estimate of the proportion of all such beams whose flexural strength exceeds 10 MPa.**Options:**- $ \hat{p} = 3 $- $ \hat{p} = 0.25 $- $ \hat{p} = 0.1875 $- $ \hat{p} = 0.125 $

A boat capsized and sank in a lake. Based on an assumption of a mean weight of 142 lb, the boat was rated to carry 60 passengers (so the load limit was 8,520 lb). After the boat sank, the assumed mean weight for similar boats was changed from 142 lb to 171 lb. Complete parts a and b below. a. Assume that a similar boat is loaded with 60 passengers, and assume that the weights of people are normally distributed with a mean of 178.5 lb and a standard deviation of 36.9 lb. Find the probability that the boat is overloaded because the 60 passengers have a mean weight greater than 142 lb. The probability is 1.000. (Round to four decimal places as needed.) C.. b. The boat was later rated to carry only 13 passengers, and the load limit was changed to 2,223 lb. Find the probability that the boat is overloaded because the mean weight of the passengers is greater than 171 (so that their total weight is greater than the maximum capacity of 2,223 lb). The probability is. (Round to four decimal…
A manufacturing company glues one part to another part during the assembly of its final product. Either too much or too little glue presents a problem. It is important for the pressure of the glue nozzle (pounds per square inch) to be set correctly because it affects the amount of glue (ounces) that is applied. Ten applications are sampled and the following information collected: SSXX = 129.6 SSYY = 2.345 SSXY = 16.6 X bar = 25.2 Y bar = 2.05 What is the estimated y intercept?
