Safety regulations state that roller coasters cannot operate safely in low temperatures. Throughout the day, ride operators measure the temperature at several random locations along the track to verify that the temperature is above an established threshold value, allowing the ride to operate safely. The collected data is used to conduct a one-sample ? -test of the null hypothesis that the mean temperature is warm against the alternative that the mean temperature is too low. If the null hypothesis is rejected in favor of the alternative, the ride is shut down due to unsafe conditions. Choose the correct description of a type I error and a type II error in this context. Type I error: - The temperature is warm enough to operate safely, and the ride is shut down. - The temperature is too low to operate safely, and the ride continues to operate. - The temperature is warm enough to operate safely, and the ride continues to operate. - The temperature is too low to operate safely, and the ride is shut down. Type II error: - The temperature is too low to operate safely, and the ride continues to operate. - The temperature is too low to operate safely, and the ride is shut down. - The temperature is warm enough to operate safely, and the ride continues to operate. - The temperature is warm enough to operate safely, and the ride is shut down.

Safety regulations state that roller coasters cannot operate safely in low temperatures. Throughout the day, ride operators measure the temperature at several random locations along the track to verify that the temperature is above an established threshold value, allowing the ride to operate safely. The collected data is used to conduct a one-sample ? -test of the null hypothesis that the mean temperature is warm against the alternative that the mean temperature is too low. If the null hypothesis is rejected in favor of the alternative, the ride is shut down due to unsafe conditions. Choose the correct description of a type I error and a type II error in this context.

Type I error:

- The temperature is warm enough to operate safely, and the ride is shut down.

- The temperature is too low to operate safely, and the ride continues to operate.

- The temperature is warm enough to operate safely, and the ride continues to operate.

- The temperature is too low to operate safely, and the ride is shut down.

Type II error:

- The temperature is too low to operate safely, and the ride continues to operate.

- The temperature is too low to operate safely, and the ride is shut down.

- The temperature is warm enough to operate safely, and the ride continues to operate.

- The temperature is warm enough to operate safely, and the ride is shut down.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
