When using the formula, use 1/6 instead of changing to a decimal. Round your answer to 1 decimal place. C. Compute the lower bound of the prediction interval. Round your answer to the nearest whole number. D. Compute the upper bound of the prediction interval. Round your answer to the nearest whole number.

Use the z-score formula, z=x−μ/σ, and the information below to find the value of σ. Round your answer to one decimal place, if necessary. z=−4.40, x=20.43 and μ=28.79

Determine the percentage error in each scenario. Show your work on all problems!!   A dad holds five coins in his hand. He tells his son that if he can guess the amount of money he is holding within 5% error, he can have the money. The son guesses that dad is holding 81 cents. The dad opens his hand and displays 90 cents. Did the son guess close enough to get the money?  A science teacher tells her class that their final project requires students to measure a specific variable and determine the velocity of a car with no more than 2.5% error. Jennifer and Johnny work hard and decide the velocity of the car is 34.87 m/s. The teacher informs them that the actual velocity is 34.15 m/s. Will Jennifer and Johnny pass their final project?  A train is on its way from Chicago, IL to Madison, WI. The trip is said to last 3.15 hours. When the train arrives in Madison, the conductor notices the trip took 3.26 hours. The train company prides itself on always having its trains arrive within a 3%…

Calculate the standard score of the given x value, x = 62, where u Round your answer to two decimal places. 69.3, o = 3.4. = Answer:

Determine the two values of z such that the middle 61% of the data lie between the two z-values. Round the solutions to two decimal places, as z- values are traditionally rounded. The middle 61% of the data lie between z = and z =

A researcher claims that at least 10% of all football helmets have manufacturing flaws that could potentially cause injury to the wearer. A sample of 200 helmets revealed that 16 helmets contained such defects. Does this finding support the researcher's claim? Use a = 0.03. Find the P-value. The proportion of football helmets with flaws The P-value is i ✓ 10%. . Round your answer to four decimal places (e.g. 12.3456).

In a sample of 1,323 mosquitoes apped in Region 1, 1,045 test positive for the disease. In a sample of 1,55. mosquitoes trapped in Region 2, 1,189 test positive for the disease. Test the alternative hypothesis that the population proportion for Region 1 is greater than the population proportion for Region 2. The test statistic is z = 1.62. What is the corresponding p-value?
