The performance of sales representatives of Xiaomi Bangladesh is monitered using the monthly sales volume that they acheive. The number of mobiledevices sold by the sales representatives is known to follow a normal distribution with a mean of 425 units and a standard deviation of 55 units. Everymonth, representatives with sales volumes between 413 units and 532 units are sent to a special training workshop to further improve their sales skills.a. What is the probability that a randomly selected representative will not get sent to the training workshop?Answer in exact fraction, or rounded to at least 4 decimal places.b. Determine the 89 percentile value for the number of devices sold by the sales representatives.Answer in exact fraction, or rounded to at least 2 decimal places.unitsc. At the training workshop, representatives who placed within the bottom 14.23% of the accepted range are also enrolled in a long-term mentorshipprogram. So, what is the minimum target sales volume a representative should try to achieve if they wish to skip the mentorship program?Answer in exact fraction, or rounded to at least 2 decimal places.units

A local service station is opened 7 days per week, every day of the year. Sale of its premium grade oil is 40 cans per day, with a standard deviation of 9.15, and each can of oil costs $15. The service station reviews its inventory every Monday when a supply sales representative arrives. Assuming the station owner wants a 99.5% service probability and the lead time for delivery is 3 days, how many cans of oil should the service station order, if there are currently 55 cans of oil on the shelf?
An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 130 lb and 181 lb.

The Jamestown Steel Company manufactures and assembles desks and other office equipment at several plants. The weekly production of the Model A325 desk follows a normal probability distribution, with a mean of 200 and a standard deviation of 16. Recently, due to market expansion, new production methods have been introduced and new employees hired. The vice president of manufacturing would like to investigate whether there has been a change in the weekly production of the Model A325 desk. Is the mean number different from 200? The mean number of desks produced last year (50 weeks, because the plant was shut down two weeks for vacation) is 203.5. Test using the.01 significance level. i. The alternate hypothesis is u200. ii. The calculated value of z is 2.55. m. The decision rule is: if the computed value of the test statistic is not between -2.58 and 2.58, reject the null hypothesis. desks produced Multiple Choice (1).
