- - The management has decided to hire a new marketing director. Based on the table given and the prices staying the same, the volume of sales and the revenue show a decreasing trend. -The interview process requires the candidate to design a plan that will increase the revenue for the following year during the first 3 months. Each monthly revenue should increase by $1,000. The price for each type of fruit should not be increased by more than one dollar. One candidate offers the option to increase the sales amounts in hundreds to the values below. Is this an acceptable opyion? Will the candidate get the job? Sales in Hundreds April May June Stawberries 9 8 6 Apples 10 9 8 Pineapples 6 9 5 Monthly revenue in hundredsThe time it takes an employee to package the components of a certain product is normally distributed with μ = 7.5 and σ = 2.5 minutes. As an incentive, management has decided to give a bonus to the 20% of employees who took the shortest amount of time to package the components. Find the amount of time taken to package the components that will indicate that an employee should get a bonus. (Round your answer to two decimal places.) An employee must package components in a time ---Select--- more than less than minutes.Using the equation from line of best fit estimate the youngest age to be to have a 4.0 Line of best fit equation Y= 0.019084x+3.97814
- An economist wants to compare the economic growth rate (%) within 50 kilometers and 100 kilometers to cities in a country. He collected 6 cities of the country, and calculated the growth rates with 50km and 100km as shown in the following table. Choose an appropriate test to validate that regions within 100km have higher economic growth rate than the regions within 50km to cities. You can make certain assumptions, but need to write to indicate your assumption. Show calculations by hand.Life Span On the basis of data and projections for theyears 1910 through 2020 the expected life span ofpeople in the United States can be described by thefunction f (x) = 11.027 + 14.304 ln x years, wherex is the number of years from 1900 to the person’sbirth year.a. What does this model estimate the life span to befor people born in 1925? In 2007? (Give eachanswer to the nearest year.)b. Explain why these numbers are so different.A gardener applied chemical "Z" to plants in a flower bed. (S)he observed that the plants grew dramatically during the next two weeks. Using only the information from the previous two sentences, write a hypothesis about the effect of chemical "Z" on plants. (Note: Your hypothesis must be a testable statement.) A researcher conducted a series of experiments to test the effect of chemical “Z” on plants. The data from the experiments is summarized in the graph below. (Image of the Graph attached.) Interpret the graph above. What did the researcher learn about the effect of chemical “Z?” Based on the researcher’s graph, what can you conclude about the hypothesis you wrote for Question 7 above?
- Determine the two values of such that the middle 55% of the data lie between the two -values. Round the solutions to two decimal places, as -values are traditionally rounded. The middle 55% of the data lie between Incorrect and Incorrect . Hint: Due to symmetry, the two -values should be opposites. Also, enter the smaller -value in the first blank and the larger -value in the second blank.Q9: Assume that a researcher wants to estimate the proportion of “A” grade scorers in STAT101 course for the population of SEU students in 2020. Assume also that the proportion of “A” grade scorers in 2020 is not known. How many SEU students must be surveyed from STAT101 course in order to be 90% confident and the margin of error should not exceed two percentage points? (Given zα/2 = 1.64). 1- 1821 2- 1781 3- 1618 4- 1681A company wants to plan production for the ensuing year so as to minimize thecombined cost of production and inventory storage. In each quarter of the year, demand isanticipated to be 65, 80, 135 and 75 respectively. The product can be manufactured duringregular time at a cost of Php 16 per unit produced, or during overtime at a cost of Php 20 perunit. The given table below shows data pertinent to production capacities. The cost of carryingone unit in inventory per quarter is Php 2. The inventory level at the beginning of the firstquarter is zero.
- Due to a stocking error 50 carp are added to a lake. The carp are prolific breeders with a population growth rate coefficient of 0.5 per month. Lake managers catch and remove K carp per month. What is the minimum number of carp that must be captured and removed to ensure they are eventually eradicated?The success of a project depends on the effort level of a worker. In case of successthe revenues will be 400,000 TL whereas in case of no-success the revenues will be 0. The workercan provide a low effort level or a high effort level. The effort level cannot be observed by theprincipal. The worker requires an expected salary of 60,000 TL to provide the low effort leveland an expected salary of 80,000 TL to provide the high effort level. The success probabilitiesfor the project are 40% in case of low effort level and 80% in case of high effort level. Whatshould be the minimum bonus (that is awarded in addition to the base salary in case of success)and the base salary for the worker so that the worker has the incentives to provide the higheffort level?Ballistics Ballistics experts are able to identify theweapon that fired a certain bullet by studying the markings on the bullet after it is fired. They test the rifling(the grooves in the bullet as it travels down the barrelof the gun) by comparing it to that of a second bulletfired into a bale of paper. The speed, s, in centimeters per second, that the bullet travels through the paper isgiven by s = 3013 - 10t2 3, where t is the time afterthe bullet strikes the bale and t … 0.3 second.a. Complete the following table to find the speed forgiven values of t. b. Use the root method to find the number of secondsto give s = 0. Does this agree with the data in thetable?
