A treatment plant that sends effluent into the river claims the mean suspended solids is never above 40 mg/l. Measurements of the suspended solids in river water on n = 14 Monday mornings yield sample mean as 46 and sample standard deviation 9.4 mg/l. Based on data collected over a period of many years, it is reasonable to assume that the individual measurements follow a normal distribution. Calculate the value of t correct to 3 decimal places.
Consider the data: 136 143 147 151 158 160 161 163 165 167 173 174 181 181 185 188 190 205. Obtain a point estimate for
A research worker wants to determine the average time it takes a mechanic to rotate the tires of a car, and she wants to be able to assert with 95% confidence that the mean of her sample is off by at most 0.50 minute. If she can presume from past experience that σ = 1.6 minutes, how large a sample will she have to take? Give your answer rounded off to the nearest integer.
A process for producing vinyl floor covering has been stable for a long period of time, and the surface hardness measurement of the flooring produced has a normal distribution with mean 3.9 and standard deviation σ = 1.5. A second shift has been hired and trained and their production needs to be monitored. Consider testing the hypothesis
