A relatively simple situation is estimation of a proportion. For example, we may wish to estimate the proportion of residents in a community who are at least 65 years old. The estimator of a proportion is , where X is the number of 'positive' e.g., the number of people out of the n sampled people who are at least 65 years old). … WebbThe required sample size is 120 : Yes. This number of IQ test scores is a fairly large number : Note from the Central Limit Theorem when we have the population standard deviation and a sample size > 30, we can assume a normal distribution *****************************************************************
SOLUTION: An IQ test is designed so that the mean is 100 and
Webb13 apr. 2024 · The most commonly used measure of circadian amplitude from wearable device data, relative amplitude, is subject to the masking effect of behaviors and fails to leverage the rich information in high-dimensional data, as it only uses the sum of activity counts in time windows of pre-specified lengths.

WebbThink about what conditions you need to check. The sample size is only 12. The scenario does not give us an indication that the lengths follow a normal distribution. Therefore, let's do a normal probability plot to check whether the assumption that the data come from a normal distribution is valid.
