Commute times in the u. s. are heavily skewed to the right. we select a random sample of 200 people from the 2000 u. s. census who reported a non-zero commute time. in this sample the mean commute time is 27.5 minutes with a standard deviation of 18.9 minutes. can we conclude from this data that the mean commute time in the u. s. is less than half an hour? conduct a hypothesis test at the 5% level of significance. what is the p -value for this hypothesis test? your answer should be rounded to 4 decimal places.

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.
