What is the range in minutes? How long will approximately 99.7% of bĪssume that the IQ in the population follows a normal distribution with a mean of 100 points and a standard deviation of 10 points. What is the best calculator for statistics Symbolab offers an online calculator specifically for statistics that can perform a wide range of calculations, including standard deviation, variance, range and normal distribution. The life expectancy of batteries has a normal distribution with a mean of 350 minutes and a standard deviation of 10 minutes. a) What is the probability that a randomly selected light bulb will have a lifespan of more than 320 hours? b) To what value of L hours can the la The lifetime of a light bulb is a random variable with a normal distribution of x = 300 hours, σ = 35 hours. Computes the sum, rounded to roundvalue, of the interest amount between pmt1 and pmt2 for an amortisation schedule. What portion of a given carton of the product is expected to contain_ faulty units? (I) less than 8 (ii) more than a real or complex number, expression, list, or matrix.
