Suppose that the recovery time from the infection with a certain virus is normally distributed with a mean of 6.5 days and a standard deviation of 1.5 days. Answer each question. Draw a graph illustrating the recovery time. Make sure to indicate 3 standard deviations from the mean. P(X>7.3)=? P(X <4.7)=? P(5.1<X<7.7)=? John's recovery time is lasting more than 9.2 days. Is it unusual (and should he be concerned yet)? What is the middle 90% recovery time? What is the 80%tile recovery time?

Hydrangea is a flower that changes its color according the the pH of the soil. The flower becomes blue when the pH of the soil is too acidic (pH below 5.5), red when the pH of the soil is too basic (pH above 6.5), and purple when the pH of the soil is exactly between 5.5 to 6.5. A landowner claims that the average pH of their soil can produce perfectly consistent purple flowers with a standard deviation pH of at most 0.5. If the standard deviation of the pH level of the soil exceeds 0.5, the flower would either become blue or red. Use a= 0.05 to determine whether you would support the landowner about the claim or not. The table below shows the pH level of 15 soil samples collected. a. This problem is a test on what population parameter? b. What is the null and alternative hypothesis c.

Hydrangea is a flower that changes its color according the the pH of the soil. The flower becomes blue when the pH of the soil is too acidic (pH below 5.5), red when the pH of the soil is too basic (pH above 6.5), and purple when the pH of the soil is exactly between 5.5 to 6.5. A landowner claims that the average pH of their soil can produce perfectly consistent purple flowers with a standard deviation pH of at most 0.5. A flower cultivator thinks the standard deviation of the pH of the soil may be greater than 0.5, so they tested 15 random sites from the land area. Use a level of significance of α = 0.05. 1) This problem is a test on what population parameter? a. Mean b. Variance / Standard Deviation c. Population Parameter 2) What is the null and alternative hypothesis? a. The standard deviation of the soil's pH IS EQUAL TO 0.5 (Ho: θ = 0.5); The standard deviation of the soil's pH DOES NOT EXCEED 0.5 (Ho: θ < 0.5) b. The standard deviation of the soil's pH IS…
Chebyshev's Theorem states that for any distribution of numerical data, at least 1-1/k? of the numbers lie within The percent of numbers between 88 and 112 is at least %. k standard deviations of the mean. (Round to the nearest hundredth as needed.) In a certain distribution of numbers, the mean is 100, with a standard deviation of 6. Use Chebyshev's Theorem to tell what percent of the numbers are between 88 and 112.

Suppose that the speeds of cars travelling on California freeways are normally distributed with a mean of 55 miles . The highway patrol's policy is to issue hour miles tickets for cars with speeds exceeding 75 The records show that exactly 1% of the speeds exceed this limit. Find the standard deviation of the speeds of hour cars travelling on California freeways. Carry your intermediate computations to at least four decimal places. Round your answer to at least one decimal place. miles hour
