Spalding Nuts and Bolts (SNB) has run out of the MX-5 Razor bolt, and must purchase
them from another state. Your research has shown that the heavier bolts seem to do better
in production. Below are average bolt weights for tvo stores that have the specialty bolts
you are looking for.

Weight of Bolts (ing.)
A. Based on visual inspection of the dotplots, which store appears to have the larger
average weight bolt? Does one store seem to have greater variability in its
weights than the other, or do the tvo stores look similar in that regard?

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.

Cor d? ? me ? max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
