All of Dave’s customers are neighbors that have yards of about the same size. Dave charges a flat rate of $35 for mowing and trimming; $50 for mowing, trimming, and fertilizing, and $25 for just mowing. Based on experience, he determines that the probability that a randomly selected customer wants him to mow, trim and fertilize the lawn is 0.55; for those who want to trim and mow the probability is 0.15, and the rest of his customers just want him to mow. Let C = the amount Dave charges a randomly selected customer. (a) Make a table that shows the probability distribution of C.

(b) Calculate and interpret the mean of C.

(c) Calculate and interpret the standard deviation of C.

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.21. what can you conclude? 2(0.21) = 0.42 < 0.5; the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time, so the test is not statistically significant. 0.21 > 0.05; the test is statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 79% of the time, so the test is not statistically significant. p = 1 - 0.21 = 0.79 > 0.05; the test is statistically significant.
