A study  examined whether or not noses continue to grow throughout a person’s lifetime.  The study included many measurements (including size of the nose as measured by total volume) and included multiple tests.  For each of the tests described below:

            a)  State the null and alternative hypotheses.

            b) Give a formal decision using a 5% significance level, and interpret the conclusion in context.

  • In a test to see whether males, on average, have bigger noses than females, the study indicates that “p < 0.01.”
  • In a test to see whether there is a positive linear relationship between age and nose size, the study indicates that “p < 0.001.”

A study was conducted to determine if a person’s agreeability (whether they are generally an agreeable person or not) affects their income level. It also looked at the person’s gender to see if it was a factor as well. The variables are shown below: Income:    y = annual income in dollars Agree:      x1 = agreeability level with higher scores indicating a person is more aggregable and lower scores indicating less agreeable Gender:   x2 = 1 if male, 0 if female...

Assuming that the world population continue to grow at its current rate, how many years would it take for the world population to grow. Hint: rate of natural increase: 0.012 is the value of "r" that you will use in the calculations below. Remember, net migration is 0 at the global level, so the rate of natural increase (RNI) is the growth rate(r) for the world population. Second, what is the size of the world population in 2018, according to...

A study examined whether the content of TV shows influenced the ability of viewers to recall brand names in commercials. The researchers randomly assigned volunteers to watch one of three​ programs, each containing the same eight commercials. The shows were either​ violent, sexual, or neutral.​ Afterwards, the subjects were asked to recall the brands of the advertised products. Results are in the accompanying table.

Write the summary. To date, however, no study specifically had examined whether and in what ways physical fitness might affect how children learn. So researchers at the University of Illinois at Urbana-Champaign recently stepped into that breach, recruiting a group of local 9- and 10-year-old boys and girls, testing their aerobic fitness on a treadmill, and then asking 24 of the most fit and 24 of the least fit to come into the exercise physiology lab and work on some...

A long-term study followed 128 women throughout their lifetime. Among the various data collected, one interesting result was that 32 of these women had suffered from a migraine at some point in their life. a) Use the results of this study and a 95% confidence interval to estimate the percentage of women in the population that will suffer from a migraine in their lifetime. Use symbols and words to express your answer. b) Use the results of this study to...

Many researchers have tried to determine whether capital punishment deters murder. Suppose a new study has been published analyzing how death-sentence rates in one year relate to murder rates the following year. The researchers who conducted this study included only the 32 states that authorize the death penalty, and excluded the remaining states. Do you think this is a justifiable approach to studying the possible deterrent effects of the death penalty? Would you trust the results of the analysis and...
