In a blind taste test, do people prefer pate or dog food? to investigate, bohannon et al. (2010) presented 18 college-educated adults with unlabeled samples of dog food and four meat products meant for humans (duck liver mousse, pork liver pate, liverwurst, and spam). participants were asked to rank their preferences. two of the 18 participants ranked the dog food first, whereas other 16 participants chose one of the other items. based on these results, can we conclude that people are statistically significantly less likely to prefer dog food over all human food?
a. what is the null hypothesis? (what would you like to reject? )
your answer
b. what is the null distribution using the number of people who prefer dog food as the test statistic?
your answer
c. what is the p-value of the observation? (use one-sided null hypothesis test where only smaller values matter)

Ur environment is very sensitive to the amount of ozone in the upper atmosphere. the level of ozone normally found is 4.04.0 parts/million (ppm). a researcher believes that the current ozone level is not at a normal level. the mean of 2525 samples is 4.44.4 ppm with a standard deviation of 0.80.8. assume the population is normally distributed. a level of significance of 0.020.02 will be used. make the decision to reject or fail to reject the null hypothesis. answer tables
