Current Attempt in Progress According to the records of an electric company serving the Boston area, the mean electricity consumption for all households during winter is 1650 kilowatt-hours per month. Assume that the monthly electricity consumptions during winter by all households in this area have a normal distribution with a mean of 1650 kilowatt-hours and a standard deviation of 320 kilowatt-hours. Find the probability that the monthly electricity consumption during winter by a randomly selected household from this area is less than 1903 kilowatt-hours. Round your answer to four decimal places.

Business Weekly conducted a survey of graduates from 30 top MBA programs. On the basis of the survey, assume the mean annual salary for graduates 10 years after graduation is $173,000. Assume the standard deviation is $32,000. Suppose you take a simple random sample of 15 graduates. Round all answers to four decimal places if necessary. What is the distribution of XX? XX ~ N(_____,______) What is the distribution of ¯xx¯? ¯xx¯ ~ N(____,_____) For a single randomly selected graduate, find the probability that her salary is between $176,006 and $185,837. ________ For a simple random sample of 15 graduates, find the probability that the average salary is between $176,006 and $185,837. ___________

According to the central limit theorem (CLT), no matter which distribution the data is collected from, as long as some conditions are met, we can always expect the sample average to behave like a normal random variable, i.e., the sampling distribution can be approximated by a normal distribution. Which is NOT a CLT condition for sample mean? Group of answer choices The original distribution of the data is Normal. A random sample with sample size is larger than 30 with no extreme outlier A random sample with sample size is less than 30 with no outliers. The sample size has to be larger than 10.
