To pay his university education, Mr. Ahmed is saving $ 1000, at the beginning of each year for the next 7 years in a Bank Muscat account paying 10% interest rate. How much will Mr. Ahmed have in that account at the end of 7^th year? Mr. Ahmed need $ 17000 to pay his university fees in future, justify your suggestion to him regarding his investment in Bank Muscat?

Computer the Depreciation Schedule by using SLD, SOYD, and DDB methods

the university pursed a lab Mass-Spectrometer that has 5 years depreciable life. The instrument costs school $900 with a Salvage Value of $70 after the end of the service life.

1. (5 pts) When they apply for graduation, students at a certain university are required to complete a brief survey about whether they felt they received sufficient value for the tuition they paid. This methodology has inherent sampling bias, particularly if the university is trying to use this data to assess whether its student population are finding value for their tuition dollar. Please describe the types of individuals and/or responses that would likely be overrepresented in this sampling methodology.

At a large university, the students have an average creditcarddebt of $2500,with a standard deviation of $1200. If we consider all of the possible random samples of 100students at this university, 95% of thesamples should have means between what two numbers? [HINT-use the 68-95-99.7Rule table in conjunction with the values for the sampling distribution model]

A)$100 and $2620

(B)$300 and $4900

(C)$2140 and $2860

(D)$2260 and $2740

In this time of crisis, the university president has asked you to use Blue Ocean Strategy to reimagine the University. Provide the analysis and let me know what your mvp would be. Be sure to indicate how your solution meets and exceeds the BOS criteria. How would it be 10x? How would the four action framework apply? What would the KPIs be?

(Computational) Applied Statistics
Problem 1: A noted medical researcher has suggested that a heart attack is less likely to occur among adults who actively participate in athletics. A random sample of 300 adults is obtained. Of that total, 100 are found to be athletically active. Within this group, 10 suffered heart attacks; among the 200 athletically inactive adults, 26 had suffered heart attacks.                   
a) Test the hypothesis that the proportion of adults who are active and sufferedheart attacks is different from the proportion of adults who are not active and suffered heart attacks.     
b) Construct a 95% confidence interval for the difference between the proportions of all active and inactive adults who suffered heart attacks.What can you conclude and why?

Problem 2: The data below refer to aluminum contents in soil at two different locations. Summary of the data is provided in the table below. You mayassume that the data are normally distributed.  
Location     n       sample mean    sample standard deviation
       1           5            2935                                235.7657
       2           4            2637                                741.8416
a) Give a 95% confidence interval for the mean aluminum contents at location 1.
b) Give a 95% confidence interval for the mean aluminum contents at location 2.
What are your conclusions from the confidence intervals in (a) and (b)and why?   
c) At , test H0 : =   versus H1 :   
d) Give the approximate p-value for the test in (c).
Problem 3: Nine students were randomly selected who had taken the TOEFL test twice. A researcher would like to test the claim that students who take the TOEFL test a second time score higher than their first test.
Student                            A       B       C        D       E        F       G      H     I
   First TOEFL Score         480   510   530   540   550   560   600   620 660
Second TOEFL Score    460   500   530   520   580   580   560 640 690
Test the claim using a level of significance of 0.05 and construct a 90% confidence interval for µd .
Problem 4: According to reported figures, the average price of used car nationally is $8,000 with a standard deviation of $4,500. A student at annajah national university wants to purchase a used car and wishes to find out if the average used car price in Nablus is less than the national average. The student collected figures on a random sample of 81 used car sales at dealerships across Nablus. The sample mean price was $7,100.
a) State the null and alternative hypotheses, compute the test statistic, find the p-value and what is your conclusion? Use α = 0.05.
b) If the actual mean of the prices is $7500, find the probability of type II error.
c) What value of n is necessary to ensure that β = 0.10 when α = 0.05 and the actual mean is $7500?

As part of a course project, a statistics student surveyed random samples of 50 student athletes and 50 student non-athletes at his university, with the goal of comparing the heights of the two groups. His summary statistics are displayed in the provided table.

a). Which data analysis method is more appropriate in this situation: paired data difference in means or difference in means with two separate groups? Explain briefly.

b). Construct a 99% confidence interval for the difference in mean heights between student athletes and non-athletes at this university. Use two decimal places in your margin of error.

c). Test, at the 5% level, if student athletes at this university are significantly taller, on average, than student non-athletes. Include all of the details.

11. (20) GPA distribution in UPW university is a normal distribution with an average of 2.68 and a standard deviation of 0.4.

(a) About what proportion of the students have GPA at most 3?

(b) About what proportion of the students’ GPA are between 2 and 3?

(c) The President of the university is establishing a new scholarship, the minimum qualification is that students GPA have to be among top 3%, what is the numerical GPA a student must have in order to qualify?

(d) A students’ club has a minimum GPA requirement of 2.7 or higher. You heard that Kelly is going to attend a club members’ meeting, you are wondering: what is the chance that Kelly’s GPA is lower than 3.3?

(e) If we randomly choose 7 students in the university, what is the chance that at least 2 have GPA over 3.3?
