Coal is carried from a mine in West Virginia to a power plant in New York in hopper cars on a long train. The automatic hopper car loader is set to put 53 tons of coal into each car. The actual weights of coal loaded into each car are normally distributed, with mean u = 53 tons and standard deviation o = 1.3 ton. n USE SALT (a) What is the probability that one car chosen at random will have less than 52.5 tons of coal? (Round your answer to four decimal places.) (b) What is the probability that 42 cars chosen at random will have a mean load weight x of less than 52.5 tons of coal? (Round your answer to four decimal places.)
The general population (Population 2) has a mean of 30 and a standard deviation of 5, and the cutoff Z score for significance in a study involving one participant is 1.96. If the raw score obtained by the participant is 45, what decisions should be made about the null and research hypotheses?
A restaurant claims that it's hamburgers had no more than 10 g of fat. You work for nutritional health agency and are asked to test this claim. You find a random sample of nine has a mean that content of 13.5 g and standard deviation of 5.8 g. At a equals 0.10, do you have enough evidence to reject the restaurants claim.
Coal is carried from a mine in West Virginia to a power plant in New York in hopper cars on a long train. The automatic hopper car loader is set to put 70 tons of coal into each car. The actual weights of coal loaded into each car are normally distributed, with mean u = 70 tons and standard deviation o = 1.4 ton. n USE SALT (a) What is the probability that one car chosen at random will have less than 69.5 tons of coal? (Round your answer to four decimal places.) (b) What is the probability that 30 cars chosen at random will have a mean load weight x of less than 69.5 tons of coal? (Round your answer to four decimal places.) (c) Suppose the weight of coal in one car was less than 69.5 tons. Would that fact make you suspect that the loader had slipped out of adjustment? O Yes O No Suppose the weight of coal in 30 cars selected at random had an average x of less than 69.5 tons. Would that fact make you suspect that the loader had slipped out of adjustment? Why? O Yes, the probability that…
U You “clock" 27 of Caruthers' fastballs, obtaining a mean of 118.7 mph, with a standard deviation of 2.2 mph. To a 1% level of significance, can it be asserted that the average Caruthers fastball (in general) is over 115 mph? JAssume that the “speeds" of all of Caruthers' fastballs are normally distributed.]
The waiting time to get food at a fast-food restaurant is 4.7 minutes on average with standard deviation of 2.5 munutes. Suppose that a sample of 32 customers is randomly selected. A. What are the mean and standard deviation of the sample mean waiting time of 32 customers? Mean = Standard Deviation (standard error of the mean) minutes minutes Round standard error to 5 decimal places. B. What is the probability that the average waiting time of 32 customers is less than 4.4 minutes? Round to 4 decimal places. C. What is the probability that the average waiting time of 32 customers is greater than 4.8 minutes? Round to 4 decimal places. D. What is the probability that the average waiting time of 32 customers is between 4.4 and 4.8 minutes? Answer: Answer:
You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly more than 0.23. Thus you are performing a right-tailed test. Your sample data produce the test statistic z = 2.831. Find the p-value accurate to 4 decimal places. p-value =
The mean number of eggs per person eaten in the United States is 266. Do college students eat a different number of eggs than the average American? The 61 college students surveyed averaged 285 eggs per person and their standard deviation was 72.6. What can be concluded at the a= 0.10 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Но: v Select an answer H.: vSelect an answer c. The test statistic ? (please show your answer to 3 decimal places.) d. The p-value = e. The p-value is ? f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... (Please show your answer to 4 decimal places.) a O The data suggest that the sample mean is not significantly different from 266 at a = 0.10, so there is statistically insignificant evidence to conclude that the sample mean number of eggs consumed by college students per year is different from 285. O The data suggest that the…
