When can the Empirical Rule be used to identify unusual results in a binomial​ experiment? Why can the Empirical Rule be used to identify results in a binomial​ experiment? Choose the correct answer below. A. When the binomial distribution is approximately bell​ shaped, about​ 95% of the outcomes will be in the interval from mu minus 2 np to mu plus 2 np. The Empirical Rule can be used to identify results in binomial experiments when np left parenthesis 1 minus p right parenthesis greater than or equals 10. B. When the binomial distribution is approximately bell​ shaped, about​ 95% of the outcomes will be in the interval from mu minus 2 sigma to mu plus 2 sigma. The Empirical Rule can be used to identify results in binomial experiments when np left parenthesis 1 minus p right parenthesis greater than or equals 10. C. When the binomial distribution is approximately bell​ shaped, about​ 95% of the outcomes will be in the interval from mu minus 2 sigma to mu plus 2 sigma. The Empirical Rule can be used to identify results in binomial experiments when np left parenthesis 1 minus p right parenthesis less than or equals 10. D. When the binomial distribution is approximately bell​ shaped, about​ 95% of the outcomes will be in the interval from mu minus 2 sigma to mu plus 2 sigma. The Empirical Rule can always be used to identify results in binomial experiments.

Answer:

B. When the binomial distribution is approximately bell​ shaped, about​ 95% of the outcomes will be in the interval from mu minus 2 sigma to mu plus 2 sigma. The Empirical Rule can be used to identify results in binomial experiments when np left parenthesis 1 minus p right parenthesis greater than or equals 10.

Step-by-step explanation:

The empirical rule states that in a bell shaped distribution, 68% of the data falls within 1 standard deviation of the mean; 95% of the data falls within 2 standard deviations of the mean; and 99.7% of the data falls within 3 standard deviations of the mean.

The mean is represented using μ and the standard deviation is representing using σ.  This means that 95% of the data will fall from μ-2σ to μ+2σ.

The sample size is represented using n.  The probability of success is represented as p, and the probability of failure would then be 1-p.  In order to use the empirical rule, np(1-p) must be greater than or equal to 10.
