- How do we set an "alpha level" in science? How is this related to our comparison with a "p-value"?arrow_forwardAnswer the following pleasearrow_forwardCloud seeding has been studied for many decades as a weather modification procedure. The rainfall in acre-feet from 20 clouds that were selected at random and seeded with silver nitrate follows, 18.0, 30.7, 19.8, 27.1, 22.3, 18.8, 31.8, 23.4, 21.2, 27.9, 31.9, 27.1, 25.0, 24.7, 26.9, 21.8, 29.2, 34.8, 26.7, and 31.6. Assume this sample data follows a normal distribution. (a) Assume that the true standard deviation of the rainfall is σ = : 4. Can you support a claim that mean rainfall from seeded clouds exceeds 25 acre-feet. Use α = = 0.01.arrow_forward
- how do I solve this problem?? I keep getting it incorrect and don't understand whyarrow_forwardAverage is 16.7, standard deviation is 3.6, what's x only 14% lower than?arrow_forwardIf age were held fixed, but a person put on 15 pounds, what would you expect for the corresponding change in systolic blood pressure? (Use 2 decimal places.)If a person kept the same weight but got 15 years older, what would you expect for the corresponding change in systolic blood pressure? (Use 2 decimal places.)(e) Test each coefficient to determine if it is zero or not zero. Use level of significance 5%. (Use 2 decimal places for t and 3 decimal places for the P-value.) t P value β2 β3arrow_forward
- How do you find standard deviation?arrow_forwardSuppose that we doubled everyone's original salary what will happen to the mean and sdarrow_forwardSuppose that the TSH (Thyroid Stimulating Hormone) levels among healthy individuals are normally distributed with a mean of 3.2 units/mL. Suppose also that exactly 98% of healthy individuals have TSH levels below 6.1units/mL. Find the standard deviation of the distribution of TSH levels of healthy individuals. Carry your intermediate computations to at least four decimal places. Round your answer to at least two decimal places.arrow_forward
