Please ASAP. Thankyou.

15) Group-A (a) Let 1 and 2 be unbiased estimators for the parameter 0. Is the estimator 03 = 0.2 0₁ + 0.8 0₂ an unbiased estimator, if yes, why, if not, why not? Explain your answer. (b) Suppose there are n individuals in a group each shooting once at the same target, where each individual can independently hit the target with the probability of 90%. Assuming the probability that at least one of them hits the target is 99.99%, determine the value of the integer n. Use a calculator to simplify your answer. (c) Noting that you do not need to explain your answer, state whether the following statement regarding the sample mean is true or false: "An increase in the number of samples or an increase in the confidence level can make the confidence interval narrower."

HW Matlab 1) Create a variable fiemp to store a temperature in degrees Fahrenheit (F). Write m-file to convert this to degrees Celsius and store the result in a variable ctemp. The conversion factor is C = (F —32) * 5/9. 2) Write m-file to generate a matrix of random integers of size 100 by 100 their values between 15 to 80. 3) Free fall of objects is given by y =5mgt? where a is the acceleration, v is the velocity, y is the distance, m is the mass of the object, g is the gravitational acceleration. Plot the distance and velocity of the object for 15 seconds after its fall from rest (y = 0). Take m = 0.2 kg.

pressure measuring system consist of piezoelectric transducer, a charge amplifier and ultra violet charge recorder. Their sensitivities are 6.8 pC/bar, 0.0032 V/pC and 16mm/V respectively. Determine , i. Overall sensitivity of the measuring system. ii. Output of the pressure measuring system for a pressure change of 20bar. iii. Deflection of the system
