The stevens motor company is developing high powered engines for use in its new sports coupe. the engineers have advertised that the maximum horsepower for the engine is 600hp. they sampled 16 engines and found the average to be 620hp (σ = 50). if the engineers sampled a larger number of engines, what would happen to the width of the confidence interval?

Browning labs is testing a new growth inhibitor for a certain type of bacteria. the bacteria naturally grows exponentially each hour at a rate of 6.2%. the researchers know that the inhibitor will make the growth rate of the bacteria less than or equal to its natural growth rate. the sample currently contains 100 bacteria.the container holding the sample can hold only 300 bacteria, after which the sample will no longer grow. however, the researchers are increasing the size of the container at a constant rate allowing the container to hold 100 more bacteria each hour. they would like to determine the possible number of bacteria in the container over time.create a system of inequalities to model the situation above, and use it to determine how many of the solutions are viable.
