- Records for the last 15 years have shown that the average rainfall in a certain region of the country, for the month of March, to be 1.20 inches, with s = 0.45 inches. A second region had an average rainfall of 1.35 inches, with s = 0.54. estimate the difference of the true average rainfalls in those two regions as a 95% C.I. with the assumption of normal populations and unequal variances.The weights of a bag of cement admixture produced by a company is approximately normally distributed with a mean of 9.0 kilograms and a variance of 0.64 kilogram. If measurements are recorded to the nearest tenth of a kilogram, find the proportion of these bags with weights (a) of at most 8.4 kilograms; (b) between 7.1 and 9.2 kilograms inclusive. (With continuity correction)In a certain city, the daily consumption of electricpower in millions of kilowatt-hours can be treated as arandom variable having a gamma distribution with α = 3and β = 2. If the power plant of this city has a daily capacity of 12 million kilowatt-hours, what is the prob-ability that this power supply will be inadequate on any given day?
- The City Council proposed to utilize government-owned land with an area of 21,600 square meters. One-third of the area will be used to plant mango trees while the rest of the land is where an emergency field hospital shall be built. As the city engineer, you were tasked to determine the rate at which the total average number of COVID cases is increasing at x=10 tents and dxdt=1 tent per day,given that if 25 tents are built, the average number of COVID cases per tent will be 6 cases while the average number of cases will increase by 2 per tent for each additional tent in the same area due to overcrowding.It is known that the tensile strength of a plastic increases as a function of the time it is subjected to heat treatment. The table below shows the data of the plastic subjected to heat treatment. Determine these data by using the "lagrange interpolation" method by approximating the functions of the lagrange multipliers of L0 , L1 , L2 , L3 and L4 to a 4th order curve. Calculate the tensile strengths of 1.7321 and 2.2361 seconds for each lagrange factor in the function equations of the lagrange multipliers.The owner of a moving company typically has his most experienced manager predict the total number of labor hours that will be required to complete an upcoming move. This approach has proved useful in the past, but the owner has the business objective of developing a more accurate method of predicting labor hours. In a preliminary effort to provide a more accurate method, the owner has decided to use the number of cubic feet moved as the independentvariable and has collected data for 36 moves in which the origin and destination were within the borough of Manhattan in New York City and in which the travel time was an insignificant portionof the hours worked. The intercept for the sample regression line that the owner has computed is -2.37 and the slope is 0.04. If the actual number of labor hours for moving 407 cubic feet is 33.47. What is the error of prediction? Hint: Provide answer accurate to 2 decimal places.
- The molecular weight of a particular polymer should fall between 750 and 1,035. Thirty samples of this material were analyzed with the results X-bar = 902 and s = 90. Assume that molecular weight is normally distributed.when using delta method to calculate variance, shouldn't [g'(μ)]^2 equal to (θ+1)^4?Jarrid Medical, Inc., is developing a compact kidney dialysis machine, but its chief engineer,Mike Crowe, is having trouble controlling the variability of the rate at which fluid moves through the device. Medical standards require that the hourly flow be 4 liters, plus or minus0.1 liter, 80 percent of the time. Mr. Crowe, in testing the prototype, has found that 68percent of the time, the hourly flow is within 0.08 liter of 4.02 liters. Does the prototype satisfythe medical standards?

Help me with 13 please.The City Council proposed to utilize government-owned land with an area of 21,600 square meters. One-third of the area will be used to plant mango trees while the rest of the land is where an emergency field hospital shall be built. As the city engineer, you were tasked to determine the following: The rate at which the total average number of COVID cases is increasing at x=10 tents and dxdt=1 tent per day, given that if 30 tents are built, the average number of COVID cases per tent will be 7 cases while the average number of cases will increase by 2 per tent for each additional tent in the same area due to overcrowding.
