Two independent experiments are run in which two different types of paint are computed. Eighteen specimens are painted using type A, and drying time (in hours) is recorded each. The same is done with type B. The population standard deviations are both known to be 1.0. Assume that the mean drying time is equal for the two types of paint, find P(X-X >1.0), where XA and Xg are average drying times for samples of size na = na = 18.

A soil is mixed at a water content of 16% and compacted in a 1000 ml cylindrical mold. The sample extruded from the mold has a mass of 1620 g, and the specific gravity of the soil grains is 2.69. Find the following: a. void ratio, b. degree of saturation, and c. dry unit weight of the compacted sample. d. If the sample is soaked in water at the same void ratio, what would be the new water content?

16. The average inside diameter of a sample of 2,000 washers produced by a machine is 0.550 inches with a standard deviation of 0.007 inches. These washers are manufactured with a maximum allowable tolerance in the diameter from 0.529 to 0.571 inches; otherwise, the washers are considered defective. Determine the number of defective washers produced by the machine, assuming that the diameters are normally distributed. (Round off your answer in whole number and without unit)

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."

Q.1) Assume that the control of a bottle filling system is performed with an 8051 microcontroller. • The start and stop of the conveyor is controlled by the P1.0 pin. • The bottles are moving on the conveyor and detected with a sensor. When they arrive at the filling place, they are detected with a logical "1" signal, otherwise they are detected with a "0" signal. • A valve connected to P1.1 turns on for 10 seconds to fill each bottle. • At every X bottles, the conveyor will stop for 8 minutes and then start again. The remaining time to restart in the waiting period is displayed in minutes on the 7-segment display. • Logic "1" is detected from P1.3 during the operation of the system. Logic '0' is detected from P1.3 at the end of the shift. • At the end of the shift, the number of the filled bottles will be determined and saved in a memory location as 2 bytes. Write the required program. (Crystal Frequency:12MHZ). NOTE: X number will be taken as the last 2 digits of 59
