The legal limit for the amount of suspended solids discharged into rivers is 60mg/liter/day. A study of water samples taken from discharges at a phosphate mine reveals that, over a long period, the average daily discharge of suspended solids is 48mg per litre, but that from day to day the discharges are variables. In order to estimate the variability of the discharges between days, a random sample of 20 days was taken and the discharges were measured. In this sample, the variance was 39(mg/l)2 We want to give an interval estimate at 90%

An Ectopic Pregnancy is twice as likely to develop when the pregnant women is a smoker as it is when she's a nonsmoker. If 32 percent of women of childbearing age are smokers, what percentage of women having Ectopic Pregnancy are smokers?
Over the past 40 years, the percentage of homes in the United States with smoke detectors has risen steadily and has plateaued at about 96% as of 2015.† With this increase in the use of home smoke detectors, what has happened to the death rate from home fires? Suppose the following contains 17 years of data on the estimated percentage of homes with smoke detectors and the estimated home fire deaths per million of population. Percentage ofHomes withSmoke Detectors Home Fire Deathsper Millionof Population 0.52 22.8 0.69 20.7 0.76 17.2 0.78 20.4 0.79 19.3 0.84 18.8 0.83 17.5 0.87 16.1 0.88 13.5 0.90 14.3 0.92 14.2 0.94 12.9 0.95 10.8 0.96 10.8 0.97 10.1 0.96 8.3 0.96 8.0 (a) Do you expect a positive or negative relationship between smoke detector use and deaths from home fires?

An fruit grower knows from previous experience and careful data analysis that if the fruit on a specific kind of tree is harvested at this time of year, each tree will yield, on average, 126 pounds, and will sell for $4.7 per pound. However, for each additional week the harvest is delayed (up to a point), the yield per tree will increase by 1.8 pounds, while the price per pound will decrease by $0.06.A) How many weeks should the grower wait before harvesting the apples in order to maximize the sales revenue per tree? (Round your answer to the nearest tenth of a week.)

An engineer creates a model to predict the electric consumption of a household in summer in a day with a predictor variable of the number of hours the air-conditioner is running. The electric consumption is only at 26 kWh per day if aircon is not used. If the aircon was used by 1 hr, the electric consumption would increase by an additional 1.44 kWh. Find the average electric consumption if the aircon is used 15 hrs.
