Imagine that a researcher wants to test the hypothesis that the mean family income in San Francisco is greater than $100,000/year. The researcher randomly samples 10 families from San Francisco and records the annual income of each family. The mean of this sample is $105,000. The researcher then performs a one-sample t test to compare this with $100,000. In this statistical analysis, which of the following statements are true? a. the null hypothesis is that the population mean is $100,000
b. the population is the set of all families in San Francisco
c. if the p value from this analysis is less than .05, the researcher will have strong evidence that the mean family income in San Francisco is greater than $100,000/year
