The data below represent the length (in miles) of a random sample of tornadoes in a specific area. This length represents the number of miles a particular tomado was on the ground. Use the data to complete parts (a) through (d) below. Click the icon to view the table of tomado lengths. No, because there are no values that fall at least 1.5(IQR) outside of Q, or Q3- Yes, because there are several values that are more extreme than Q₁ or Qgg- Yes, because there are several values that fall at least 1.5(IQR) outside of Q, or Q3. No, because there are no values that are more extreme than Q, or Qgg- (c) Based on the results to parts (a) and (b), explain why a large sample size might be desirable to construct a confidence interval for the mean length of a tornado in this area. Choose the correct answer below. A. The results to parts (a) and (b) indicate that the underlying population is non-normal. Such populations require large sample sizes to construct valid confidence intervals. OB. The results to parts (a) and (b) indicate that the sample data are not independent. Dependent samples require large sample sizes to construct valid confidence intervals. OC. The results to parts (a) and (b) indicate that the underlying population is normal. Such populations require large sample sizes to construct valid confidence intervals. D. The results to parts (a) and (b) indicate that the sample size is small relative to the population size. Sample sizes must be large relative to the population size to construct valid confidence intervals. O M (d) Use statistical software to construct a 99% confidence interval for the mean tomado length.
