Built-Tight is preparing its master budget for the quarter ended September 30, 2017. Budgeted sales and cash payments for product costs for the quarter follow:

Sales are 20% cash and 80% on credit. All credit sales are collected in the month following the sale. The June 30 balance sheet includes balances of $15,000 in cash; $44,200 in accounts receivable; $3,700 in accounts payable; and a $4,200 balance in loans payable. A minimum cash balance of $15,000 is required. Loans are obtained at the end of any month when a cash shortage occurs. Interest is 1% per month based on the beginning-of-the-month loan balance and is paid at each month-end. If an excess balance of cash exists, loans are repaid at the end of the month. Operating expenses are paid in the month incurred and consist of sales commissions (10% of sales), office salaries ($3,200 per month), and rent ($5,700 per month).

(1) Prepare a cash receipts budget for July, August, and September.

(2) Prepare a cash budget for each of the months of July, August, and September. (Negative balances and Loan repayment amounts (if any) should be indicated with minus sign. Enter your final answers in whole dollars.)

calculate built-in potential, maximum electric field and width of the depletion layer in Si p-n diode doped with donors and acceptors to concentration of 2x10^17cm^-3 and 5x10^16 cm^-3 respectively

estimate the maximum voltage which can be safely applied to the diode descibed above

estimate density of reverse current in the diode desribed in top if the diffusion constants and the diffusion lengths of holes and electrons are about 30cm^2/s and 100mm respectively

Consolidated Power, a large electric power utility, has just built a modern nuclear power plant. This plant discharges waste water that is allowed to flow into the Atlantic Ocean. The Environmental Protection Agency (EPA) has ordered that the waste water may not be excessively warm so that thermal pollution of the marine environment near the plant can be avoided. Because of this order, the waste water is allowed to cool in specially constructed ponds and is then released into the ocean. This cooling system works properly if the mean temperature of waste water discharged is 66^oF or cooler. Consolidated Power is required to monitor the temperature of the waste water. A sample of 100 temperature readings will be obtained each day, and if the sample results cast a substantial amount of doubt on the hypothesis that the cooling system is working properly (the mean temperature of waste water discharged is 66^oF or cooler), then the plant must be shut down and appropriate actions must be taken to correct the problem.

(a) Consolidated Power wishes to set up a hypothesis test so that the power plant will be shut down when the null hypothesis is rejected. Set up the null and alternative hypotheses that should be used.

H₀: µ (Click to select)?> 66 versus H_a: µ (Click to select)?> 66 where µ = mean temperature of waste water.

(b) In the context of this situation, interpret making a Type I error; interpret making a Type II error.

Type I error: decide µ (Click to select)?> 66 (shut down) when µ (Click to select)>? 66 (water is cool enough, no shutdown needed)

Type II error: decide µ (Click to select)>? 66 (do not shut down) when µ (Click to select)>? 66 (water is too warm shutdown needed)

(c) The EPA periodically conducts spot checks to determine whether the waste water being discharged is too warm. Suppose the EPA has the power to impose very severe penalties (for example, very heavy fines) when the waste water is excessively warm. Other things being equal, should Consolidated Power set the probability of a Type I error equal to ? = .01 or ? = .05?

Set ? = 0.05 to make the probability of a (Click to select)Type IIType I error (Click to select)largersmaller.

University Car Wash built a deluxe car wash across the street from campus. The new machines cost $240,000 including installation. The company estimates that the equipment will have a residual value of $30,000. University Car Wash also estimates it will use the machine for six years or about 12,000 total hours. Actual use per year was as follows: Year Hours Used 1 2,600 2 2,100 3 2,200 4 1,800 5 1,600 6 1,700 1. Prepare a depreciation schedule for six years using the straight-line method.

CAN YOU PLEASE POST THE R-SCRIPT ONLY

The built-in data set LakeHuron is a time series which provides records of annual measurements of the level, in feet, of Lake Huron 1875 to 1972. Using R we can convert this data into the vector x by the assignment x<-as.vector(LakeHuron). Assume that the n measurements x=(

x₁, x₂,...,x_n) are a random sample from a population with true unknown mean μ and true unknown variance σ². Remember, let x be defined by x<-as.vector(LakeHuron)

CAN YOU PLEASE POST THE R-SCRIPT ONLY
a) Calculate, n, the number of elements in x.

b)Calculate the sample standard deviation s, of x.

c) Estimate true mean μ, using this data by calculating the sample mean.

d) Calculate an unbiased point estimate of the population variance, σ² of faithful waiting times.

e) Assuming normality of LakeHuron levels, calculate the maximum likelihood estimate of μ?

f) Calculate the 70th percentile of x using R.

Calculate a 2/98 trimmed mean for x using R.

h) Since the sample size is >30 we can create a confidence interval for μ using a normal critical value. If we want the confidence interval to be at the 97% level and we use a normal critical value, then what critical value should we use?

i) Calculate a 97% confidence interval(using a normal critical value) for μ.

j) How long is the 97% confidence interval just created in part i?
