The American College of Cardiologists claims that the mean number of grams of fat in the popular M.I. Burger sold at Burgers To Die For is 24 grams with σ = 5 grams. If a sample of 50 M. I. Burgers is taken, what is the probability that the sample mean is 25 grams or more?
When answering this question on an assignment, you said n=10. Im confused as to why you said this/where this came
The probability that a bomber hits its target on any particular mission is 0.80. Four bombers are sent after the same target. What is the probability: they all hit the target?
From the given polynomials, identify the polynomials of degree one. A function gives the value of C as 2 × (22/7) × r. Find C when r = 7 cm and r = 91 cm.
This yields 4 conditions: normal, mean (0 for errors, constant within treatment), constant variance and independent. B)(3) From the output given, are the assumptions in part a) satisfied?
The prices (in dollars) for a sample of roundtrip flights from Chicago, Illinois to Cancun, Mexico are listed. Find the mean, median, mode, range, Q1, Q2, variance, and standard deviation of the flight prices.
At the 5% significance level, if the sample proportion is .45, and the standard error of the sample proportion is .035, the appropriate conclusion would be:
The election is one week away. You think you have the election sewn up, but the seem appears to be unraveling. You run a poll, draw a random sample of 500 adults.
Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviation are equal.
What method has been used to transform Model 1 to Model 2? Equations for Model 1 and Model 2 are as follows:
Based on past information, for the cars used, the distance traveled by a car in a day averages 170 km with a standard deviation of 40 km. What proportion of cars used in any day travel less than 100 km?
Draw frequency polygons for each of the four distributions (assume they are normal) with the raw scores indicated for all six of the standard deviation units. a) Mean= 15 SD= 3
Construct a 95 percent confidence interval for the true mean.
