Determine whether the results below appear to have statistical significance, and also determine whether the results have practical significance.In a study of a weight loss program, 5 subjects lost an average of 50 lbs. It is found that there is about 28% chance of getting such results with a diet that has no effect.Part A. Does the weight loss program have statistical significance?a. No, the program is not statistically significant because the results are likely to occur by chance.b. Yes, the program is statistically significant because the results are unlikely to occur by chance.c. No, the program is not statistically significant because the results are unlikely to occur by chance.d. Yes, the program is statistically significant because the results are likely to occur by chance.PART B. Does the weight loss program have practical significance?a. Yes, the program is practically significant because the results are too unlikely to occur by chance.b. No, the program is not practically significant because the amount of weight lost is trivial.c. No, the program is not practically significant because the results are likely to occur even if the weight loss program has no effect.d. Yes, the program is practically significant because the amount of lost weight is large enough to be considered practically significant

A contaminant is leaking into a lake at a rate of R(t) = 1700e^0.06t gal/h. Enzymes that neutralize the contaminant have been added to the lake over time so that after t hours the fraction of contaminant that remains is S(t) = e^−0.32t. If there are currently 10,000 gallons of the contaminant in the lake, how many gallons will be present in the lake 17 hours from now? (Round your answer to the nearest integer.)

The article "Influence of Penetration Rate on Penetrometer Resistance" (see textbook for reference) presents measures of penetration resistance for a certain fine-grained soil. Fifteen measurements, expressed as a multiple of a standard quantity, had a mean of 2.64 and a standard deviation of 1.02. Find a 95% of confidence interval for the mean penetration resistance for this soil.
