Writer did an excellent job on completing the discussion board assignment questions in a timely manner and the revising. I will be hiring this writer for future assignments.
If you flip a coin three times, the possible outcomes are HHH, HHT, HTH, HTT, THH, THT, TTH, TTT. What is the probability of getting at most one head?


A study of two types of weed killers was done on two identical weed plots. One weed killer killed 15% more weeds than the other. This difference was significant at the 0.05 level. What does this mean?

Which graph has two groups of data, correlations within each group, but no correlation among all the data?


A sample of 64 statistics students at a small college had a mean mathematics ACT score of 28 with a standard deviation of 4. Estimate the mean mathematics ACT score for all statistics students at this college. Give the 95% confidence interval.


Among a random sample of 150 employees of a particular company, the mean commute distance is 29.6 miles. This mean lies 1.2 standard deviations above the mean of the sampling distribution. If a second sample of 150 employees is selected, what is the probability that for the second sample, the mean commute distance will be less than 29.6 miles?


Which line of the three shown in the scatter diagram below fits the data best?


Select the best fit line on the scatter diagram below.


The scatter plot and bestfit line show the relation between the price per item (y) and the availability of that item (x) in arbitrary units. The correlation coefficient is 0.95. Determine the amount of variation in pricing explained by the variation in availability.
