- Suppose that a new treatment is successful in Curing a common ailment 63% of the time. If the treatments is used on 80 patients, approximate the probability that more than 50 will be cured. Use the normal approximation to the binomial with a correction for continuity. Round your answer to 3 decimal places, do not round intermediate steps.The age of children in kindergarten on the first day of school is uniformly distributed between 4.73 and 5.75 years old. A first time kindergarten child is selected at random. Round answers to 4 decimal places if possible. The mean of this distribution is The standard deviation is The probability that the the child will be older than 5 years old?Time between arrivals follows an Exponential distribution with a mean of 16.67 minutes. What is the probability of waiting more than 30 minutes for the next arrival. (estimate to the 4th decimal place)
- what is the cumulative area from the left under the curve for a Z score of -0.78? what is the area on the right of that Z score? Hint: you will have two answers (One for the left and one for the right). Students partially finished answer: The first part is to find the cumulative area from the left under the curve for a Z score of -0.78. this means that I need to find the probability that a Z score is less than -0.78. show your calculations using XL functions in the area to the right of this text box and finish answering the problem with explanations below.Suppose that a new treatment is successful in curing a common ailment 73% of the time. If the treatment is tried on a random sample of 100 patients, approximate the probability that more than 70 will be cured. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round any intermediate steps. (If necessary, consult a list of formulas.)A coin is tossed 400 times. Use the normal-curve approximation to find the probability of obtaining Between 185 and 201 heads Exactly 205 heads More than 227 heads
- Two resistors, with resistances R1 and R2, are connected in series. R1 is normally distributed with mean 100Ω and standard deviation 4Ω, and R2 is normally distributed with mean 120Ω and standard deviation 10Ω. What is the probability that R2 exceeds R1 by more than 30 Ω?The over-cumulative series plot of a classified frequency series is given below. What is the median value of the classified series?2. Today, the waves are crashing onto the beach every 5.6 seconds. The times from when a person arrives at the shoreline until a crashing wave is observed follows a Uniform distribution from 0 to 5.6 seconds. Round to 4 decimal places where possible. The mean of this distribution is ? The standard deviation is ? The probability that wave will crash onto the beach exactly 4.2 seconds after the person arrives is P(x = 4.2) = ? The probability that the wave will crash onto the beach between 0.9 and 5.1 seconds after the person arrives is P(0.9 < x < 5.1) = ? The probability that it will take longer than 1.72 seconds for the wave to crash onto the beach after the person arrives is P(x > 1.72) = ? Suppose that the person has already been standing at the shoreline for 1.2 seconds without a wave crashing in Find the probability that it will take between 2.8 and 5.3 seconds for the wave to crash onto the shoreline? 13% of the time a person will wait at least how long before the wave…

Then the interval between any two successive arrivals follows exponential distribution with mean, 1/λ=1/2 minute. Find the probability that the interval between two successive arrival is,a. more than 1 minuteb. 4 minutes or lessc. between 1 and 2 minutesDelivery times for shipments from a central warehouse are exponentially distributed with a mean of 2.81 days (note that times are measured continuously, not just in number of days). The standard deviation of an exponential distribution is equal to the mean of 2.81 days. A random sample of 65 shipments are selected and their shipping times are observed. Use the Central Limit Theorem to find the probability that the mean shipping time for the 65 shipments is less than 2.38 days.
