Which of the following is NOT a condition that ALWAYS has to be satisfied to apply the Central Limit Theorem to the sample mean? a) The sample size must be larger than 30 b) There are no obvious outliers in the sample if the sample size is less than 30 c) There are no extreme outliers in the sample if the sample size is at least 30. d) The sample observations are independent.
Which of the following statements about the Central Limit Theorem (CLT) is correct?1. The CLT states that the sample mean is always equal to the population mean.2. The CLT states that the sampling distribution of the sample mean is approximately normal for large sample sizes (n > 30).3. The CLT states that the sample mean is equal to the population mean, provided that n > 30.4. The CLT states that the sampling distribution of the population mean is approximately normal, provided that n > 30. In a distribution plot, if the mean is equal to the median, is the possible shape of the distribution skewed to the right, skewed to the left, or symmetric?

In a bag of 405 chocolate candies, 43 of them are brown. The candy company claims that 13% of its plain chocolate candies are brown. For the following, assume that the claim of 13% is true, and assume that a sample consists of 405 chocolate candies. Complete parts (a) through (e) below. a.) For the 405 chocolate candies, use the range rule of thumb to identify the limits separating numbers of brown chocolate candies that are significantly low and those that are significantly high. Values of ____ brown candies or fewer are significantly low. Values of ____ brown candies or greater are significantly high. Based on the results, is the result of 43 brown chocolate candies significantly low? Why or why not? b.) Find the probability of exactly 43 brown chocolate candies. c.) Find the probability of 43 or fewer brown chocolate candies.
Sixty-seven percent of the U.S households, or about 85 million families, own a pet, according to the 2019-2020 national pet owners survey conducted by the American pet products association (APPA).
