we sometimes see in the literature terms like, "close to significance", "approaching significance", and "borderline significance", to refer to p-values that are close to 0.05. Some investigators do not think these terms are appropriate, i.e., something is significant or is not - thus, 0.049 is significant and 0.051 is not significant. How do you feel about this issue? No right or wrong answers, as long as you justify your response (and use citations).

We would like to conduct a hypothesis test at the 5% level of significance to determine whether hockey players weigh more on average than baseball players. We record the weights of a random sample of 12 professional hockey players and 7 professional baseball players. Weights of athletes in both sports are known to follow normal distributions. Some summary statistics are given below: Sport n x s d Baseball 7 187.571 7.72 Hockey 12 195.583 18.39 Based on the data, we...

We have seen a couple of times now that action potentials occur because of the rapid switching of places of sodium and potassium ions across a plasma membrane (“Na+ IN, K+ OUT”). The influx of sodium into a cell causes depolarization of the membrane; the efflux of potassium out of a cell repolarizes the membrane. In your own words, describe how excess extracellular K+ would affect this process, if at all.

Assume that we would like to test at significance level 0.01 whether there is enough evidence to claim that average height of children by the end of age three in families with low-socioeconomic status is less than the general average height for this age, which is 94 cm. Assume that height measurements by the end of age three follow a normal distribution with standard deviation 6 cm. (a) Write the null and alternative hypothesis for the hypothesis testing procedure that...

Assume that we would like to test at significance level 0.01 whether there is enough evidence to claim that average height of children by the end of age three in families with low-socioeconomic status is less than the general average height for this age, which is 94 cm. Assume that height measurements by the end of age three follow a normal distribution with standard deviation 6 cm. For this study, assume that 9 children (from families with low socioeconomic status...

Using the data below, we would like to understand why some cities have a higher proportion of creative-class workers than others. Under one theory, the proportion may be explained only by the city’s income, while in another theory, income along with population and cost-of-living are thought to explain the proportion.. (a) Estimate a linear regression model for each theory and report your results. (b) Use an F test to choose one theory over another. (c) State the null hypothesis, the...
