- Use normal approximation to estimate the probability of getting less than 47 girls in 100 births. Assume that boys and girls are equally likely.Suppose X is a normal random variable, and E(X) = 2. Find the probability that X will be within 2 standard deviations of its expected value.Assume that adults have IQ scores that are normally distributed with a mean of u = 100 and a standard deviation o = 20. Find the probability that a randomly selected adult has an IQ between 80 and 120.
- If X is exponentially distributed with a mean of 3, can you find a uniform distribution U[a,b]with the same mean and standard deviation? please specify the values of a and b(please keep two significant numbers)Today, the waves are crashing onto the beach every 5 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 seconds. Round to 4 decimal places where possible. The probability that the wave will crash onto the beach between 1 and 2.6 seconds after the person arrives is P(1 < x < 2.6) = The probability that it will take longer than 2.5 seconds for the wave to crash onto the beach after the person arrives is P(x ≥≥ 2.5) = Find the maximum for the lower quartile. seconds.the time X that a lightbulb can last (life lenght) is a distribution with mean 1 year and standard deviation 0.5 years. suppose we have 100 such lightbulbs, what is the probability that the average life length of the lightbulks is greater than 1.02 years? what is theorem you are using here?
- Tet x be a random variable that represents white blood cell count per cubic milliliter of whole blood. Assume that x has a distribution that is approximately normal, with mean = 7650 and estimated standard deviation a = 2450. A test result of x< 3500 is an indication of leukopenia. This indicates bone marrow depression that may be the result of a viral infection. L USE SALT (a) What is the probability that, on a single test, x is less than 3500? (Round your answer to four decimal places.) (b) Suppose a doctor uses the average x for two tests taken about a week apart. What can we say about the probability distribution of x? The probability distribution of x is approximately normal with = 7650 and o, = 2450. O The probability distribution of x is not normal. 0 The probability distribution of x is approximately normal with us = 7650 and ag = 1732.41. The probability distribution of x is approximately normal with = 7650 and og = 1225.00. What is the probability of x < 3500? (Round your…Five males with an X-linked genetic disorder have one child each. The random variable x is the number of children among the five who inherit the X-linked genetic disorder.
