All trucks traveling on Interstate 40 between Albuquerqueand Amarillo are required to stop at a weigh station. Trucksarrive at the weigh station at a rate of 120 per eight-hourday (Poisson distributed), and the station can weigh, on theaverage, 140 trucks per day (Poisson distributed).a. Determine the average number of trucks waiting, the average time spent at the weigh station by each truck, and theaverage waiting time before being weighed for each truck.b. If the truck drivers find out they must remain at theweigh station longer than 15 minutes on the average,they will start taking a different route or traveling atnight, thus depriving the state of taxes. The state ofNew Mexico estimates it loses $10,000 in taxes peryear for each extra minute (over 15) that trucks mustremain at the weigh station. A new set of scales wouldhave the same service capacity as the present set ofscales, and it is assumed that arriving trucks would lineup equally behind the two sets of scales. It would…
Suppose that the diameter of meter shafts in a lot have a mean of 0.249 inches and standard deviation of 0.03 inches. The inner diameter of bearings in another lot have a mean of 0.255 inches and standard deviation of 0.002 inches.a) Find the mean and standard deviation of clearances between shafts and bearings selected from these lots.b) If a shaft and bearings are selected at random, find the probability that the shaft will not fit inside the bearings. Assume that both dimensions are normally distributed.
When the distance from the smallest observation to the 1st quartile is much greater than the distance from the 3rd quartile to the largest observation, the data set is most likely Two answers correct. 1. symmetrical. 2. nonsymmetrical. 3. skewed to the right. 4. skewed to the left. 5. not skewed.
To the Internal Revenue Service (IRS), the reasonableness of total itemized deductions depends on the taxpayer’s adjusted gross income. Large deductions, which include charity and medical deductions, are more reasonable for taxpayers with large adjusted gross incomes. If a taxpayer claims larger than average itemized deductions for a given level of income, the chances of an IRS audit are increased. Data (in thousands of dollars) on Adjusted Gross Income (AGI) and the Reasonable Amount of Itemized Deductions (RAID) are as follows: AGI : 22, 27, 32, 48, 65, 85, 120 RAID : 9.6, 9.6, 10.1, 11.1, 13.5, 17.7, 25.5 The correct interpretation of the meaning of each of the coefficients in the linear model is: a. When AGI is zero, the RAID is $4680 in this linear model. Since x = 0 is not included in the sample values of the independent variable, this interpretation cannot be a meaningful one. For every one thousand dollar of the AGI, the RAID increases by $161 in this linear model.…

An agronomist is interested in comparing the efficacy of two fumigants (A and B) and a control (O) in eliminating wireworms. A field is divided into 4 sections, each section containing 3 plots. Fumigant A, B and O were randomly assigned to one plot within each section. The number of wireworms that remained on each plot after application of fumigant was recorded. Give a possible RCBD layout for the experiment.
If the moments of a distribution do not change over time, the distribution is: 1. random 2. non-stationary 3. stationary 4. detrministic 4. storchastic
Mechanical engineer Kwok Wai Tham of the National University of Singapore set out to sample how much virus COVID-19 patients produce when they breathe, talk or sing, in part, to address skeptics’ concerns. “I’m doing this to convince some very close friends,” he says. He and colleagues rolled a mobile lab into 22 patients’ rooms and had volunteers stick their heads into a large metal cone. The researchers collected both aerosols and larger droplets that the patients exhaled while breathing quietly for 30 minutes, while repeating passages from Dr. Seuss’ Green Eggs and Ham for 15 minutes, or while singing simple tunes like the “Happy Birthday” song, “Twinkle, Twinkle Little Star” or the “ABCs” for 15 minutes. The scientists tested both aerosols and large droplets in the air samples for coronavirus RNA and calculated how many copies of the virus’s nucleocapsid protein gene, or N gene, were present. That gives an estimate of how much virus is in a sample.Of the 22 patients who sang for…
A small jet can carry up to 44 passengers and 3 crew members. There is a weight restriction of 9000 pounds on board. The combined weight of each passenger (or crew member) and his luggage has a mean of 195.4 pounds, with a standard deviation of 69.2 pounds. What is the probability that the weight limit willl be exceeded when there are exactly 44 passangers and 3 crew members on board? Carry your intermediate computations to at least four decimal places. Report your result to at least three decimal places.
Assume that females have pulse rates that are normally distributed with a mean of μ = 74.0 beats per minute and a standarddeviation of σ = 12.5 beats per minute. Complete parts (a) through (c) below.a. If 1 adult female is randomly selected, find the probability that her pulse rate is less than 80 beats per minute. b. If 16 adult females are randomly selected, find the probability that they have pulse rates with a mean less than 80 beatsper minute.c. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30? A. Since the distribution is of individuals, not sample means, the distribution is a normaldistribution for any sample size.B. Since the original population has a normal distribution, the distribution of sample means is anormal distribution for any sample size.C. Since the distribution is of sample means, not individuals, the distribution is a normaldistribution for any sample size.D. Since the mean pulse rate exceeds 30, the distribution…
