QUESTION 1 Tyre pressures on a certain type of car independently follow a normal distribution with mean 1.9 bars and standard deviation 0.15 bars. (i) Find the probability t'hat all four tyres on a car of this type have pressures between 1.82 bars and 1.92 bars. (ii) Safety regulations state that the pressures must be between 1.9-b bars and 1.9 + b bars. It is known that 80% of tyres are within these safety limits. Find the safety limits.

You purchase a brand new car for $15,000 and insure it. The policy pays 78% of the car's value if there is an issue with the engine or 30% of the car's value if there is an issue with the speaker system. The probability of an issue with the engine is 0.009, and the probability there is an issue with the speaker system is 0.02. The premium for the policy is p. Let X be the insurance company's net gain from this policy. (a) Create a probability distribution for X, using p to represent the premium on the policy. Enter the possible values of X in ascending order from left to right. P(X) (b) Compute the minimum amount the insurance company will charge for this policy. Round your answer to the nearest cent
