The sweetness of sap from maple sugar trees is measured by how many gallons of sap are required to produce one gallon of syrup. A sample of 30 sugar woods in New York yielded an average sweetness of 39 gallons with a standard deviation of 3.6 gallons. A sample of 35 sugar woods in Vermont yielded an average sweetness of 35 gallons with a standard deviation of 4.9 gallons. Test at a 2% level of significance that the sugar woods from New York required more sap than the sugar woods from Vermont to make one gallon of syrup.

Maple syrup is produced from sap of maple trees that is evaporated until the concentration of sugar (mostly sucrose is C12H22O11 molar mass: 342.3g = 1 mole) in the sap reaches at least 66% by weight. 1) What is the solute in this solution? How do you know? 2) What is the molality of this solution? Assume a 100 g solution. Please help with full answer and steps.

In recent years, Vermont has seen an influx of newcomers to maple sugaring, many spurred by higher prices and profits. And that’s been matched by use of more sophisticated technology, experts say. In days gone by, the dairy farmers would often use dairy equipment as they tapped trees and produced syrup. Today, however, Stowe said maple farmers rely on advances in equipment — such as tubing, fittings and vacuum pumps — and advances in science — such as improvements in...

A survey of entry level corporate analysts in New York City asked, approximately how many hours per week do you work? (a) If the population standard deviation is known to be 4.7 hours, and a random sample of 35 corporations yielded a mean of 50.5 hours, then construct a 90% confidence interval for the mean number of hours worked by entry level analysts. (b) In the above confidence interval, suppose that we want a margin of error of +/- 1...

Conductivity is one of many properties measured to evaluate water quality. The table below (also attached as an Excel file) contains conductivity measurements (µS/cm) of groundwater samples from a single well. First, prepare a graph of the raw data. Then set up estimates of the conductivity population average (95% CI), population standard deviation (95% CI), and a future individual measurement (95% PI). Also develop a 95% tolerance interval estimate of the conductivity that will include 99% of the conductivities. Finally,...

An experiment was carried out to measure the effect of growth hormone on girls affected by a growth disorder called Turner’s syndrome. A total 68 girls participated in the study. Half of the girls were placed into the treatment group; these girls were given the active drug. The other half of girls were placed into the control group and were given a placebo with no active ingredients. Their heights were measured at the time the hormone was first administered and...
