Exercise 2: Gestation Times The Biology Data Book reports that the gestation time for human babies averages 278 days with a standard deviation of 12 days. Suppose that these gestation times are normally distributed.

1. Find the upper and lower quartiles for the gestation times.

2. Would it be unusual to deliver a baby after only six months of gestation? Explain.

3. Find the number of days such that 90% of babies have gestation times less than or equal to this number

4. Find the number of days such that 90% of babies have gestation times larger than or equal to this number.

Biology lab question: 1. Molecular clock data place the evolution of diatoms around the time period following the Permian extinction. One hypothesis is that an adaptive radiation occurred as they colonized new marine niches. Based on what you know about the effects of ocean acidification on the formation of tests made from calcium carbonate and the composition of the tests (cell walls) of diatoms, what is a possible explanation for this diatom “explosion”? 2. what is the distinguishing features of...

2. An experiment was conducted by a physiologist to determine whether exercise improves the human immune system. Thirty subjects volunteered to participate in the study. The amount of immunoglobulin known as IgG (an indicator of long-term immunity) and the maximal oxygen uptake (a measure of aerobic fitness level) were recorded for each subject. The data can be found in the file marked AEROBIC. You will need to use the Data Analysis - Regression Function for this problem, as well as...
