Referring to the example below If a compliance rate of 95% is expected how many of the 750 charts requested could fall below the standard and still be within the 95% goal An him department has 50,000 active records on file the record supervisor has established a maximum 15 minute time. For retrieval of a record during the past month 750 charts were requested of this number 688 where retrieved within a 15 minute. What percentage of the records fell below the established standard subtracting 688 from 750 indicates that 62 charts did not meet the required standard bus 62 out of 750 retrievals were not in compliance for an 8.27% non-compliance rate

if a certain environment bill is passed by congress, the united states would have to reduce greenhouse gas emissions by 17% from 2005 levels by the year 2020. the University of New Hampshire has been at forefront of reducing emissions, and id this bill is passed they would be required to have greenhouse gas emissions level of 56,440 MTCDE by 2020. Find their approximate emission level in 2005.

Please solve and show/explain steps for (b). The answer is not (983.6, 1400.4). Thanks!

The average age of a preschool class is 4.5 years old. If there is one 3-year-old, five 5-year-olds, and two other children both of the same age, what is the age, in years, of the other two children?

The accompanying table shows the results of a survey in which 250 male and 250 female workers ages 25 to 64 were asked if they contribute to a retirement savings plan at work. Complete parts (a) and (b) below. Click the icon to view the survey results. (a) Find the probability that a randomly selected worker contributes to a retirement savings plan at work, given that the worker is male. The probability that a randomly selected worker contributes to a retirement savings plan at work, given that the worker is male, is. (Round to three decimal places as needed.)

Create two short answer questions that assess understanding of how to add within 100, including using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction

The Dorben Co. uses a standard hour plan with a base wage of $9/h. It hires an IE consultant to plan a batch production run of 300 units. This consultant has a worker on the line produce 2 units. The first takes 10 min and the second 9.7 min. Assuming that the worker continues to improve her performance, what will she be paid for the full batch of 300 units under the standard hour plan? What is the unit cost for the first unit made? What is the cost for 300th unit? there is already an answer for this question in chegg but it does not explain clearly in steps. I need some clear explanation thnks

The scores of a test for an engineering class of 30 students are shown here. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) Scores: 81, 54, 55, 56, 96, 86, 98, 61, 90, 52, 92, 76, 66, 84, 79, 70, 71, 88, 62, 74, 53, 65, 55, 78, 79, 58, 60, 72, 51,80 (a) Determine the frequency (f), midpoint (x), and xf for each range and fill in the table below. (First, organize the scores into the following ranges: 50-59, 60-69, 70-79, 80-89, and 90-99.) (b) Using the following equation, determine the mean value (x) and fill in the table below. Σ(XA) n X = (c) Calculate (x − x) for each range and fill in the table below. (d) Calculate (x - x)²f for each range and fill in the table below. Range Frequency f Midpoint x 50-59 60-69 70-79 80-89 90-99 S = Enter a number. S = (e) Using the following equation, compute the standard deviation of the class scores.

Several years ago, the Arcadia school system was criticized because the average Arcadia High School graduate could read at only the ninth-grade level.  After this report was made, a special reading program was established to upgrade skills.  The AHS principal wants to know if the reading program worked.  If it has, he will request that an accreditation team visit the school.  If the program has not improved the reading level to at least 10.0 (sophomore level), the administrator would like to avoid the embarrassment of a poor review.  To determine the average reading level of the senior class, we select ten seniors at random.  We assume that reading scores are normally distributed.  The reading scores for the ten seniors are shown in Table 1.   Table 1: Reading Scores for Sample High School Seniors Student Reading Score 1 13.4 2 12.1 3 11.4 4 10.6 5 10.3 6 10.2 7 9.8 8 9.7 9 9.4 10 8.6   Calculate the sample mean…
