Give the answer to 4 decimal places as needed.Suppose 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 99% of healthy individuals have TSH levels below 5.8 units/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.
- In a sample of 15 randomly selected high school seniors, the mean score on a standardized test was 1180 and the standard deviation was 164.3. Further research suggests that the population mean score on this test for high school seniors is 1020. Does the t-value for the original sample fall between - to 90 and to 90? Assume that the population of test scores for high school seniors is normally distributed. The t-value of t = fall between - to.90 and to.90 because to.90 %3D (Round to two decimal places as needed.)Assume that z-scores are normally distributed with a mean of 0 and a standard deviation of 1.If P(−b<z<b)=0.1904, find b.If the variable Z is normally distributed with mean equal to 0 and standard deviation equal to 1.
