Assume a math professor who teaches differential calculus discovered that the average course grade prior to COVID was 73.8. During the COVID lockdowns, this calculus professor remotely taught a differential calculus class to 124 students with an average course grade of 78.9 and a sample standard deviation of 11.1. Is this a very high course grade? Use ?(something look a) =0.05.

A certain group of test subjects had pulse rates with a mean of 75.2 beats per minute and a standard deviation of 11.2 beats per minute. Use the range rule of thumb to identify the limits separating values that are significantly low or significantly high. Is a pulse rate of 147.6 beats per minute significantly low or significantly high? Significantly low values are 52.8 beats per minute or lower. (Type an integer or a decimal. Do not round.) Significantly high values are 97.6 beats per minute or higher. (Type an integer or a decimal. Do not round.) Is a pulse rate of 147.6 beats per minute significantly low or significantly high? O A. Significantly low, because it is more than two standard deviations below the mean. O B. Neither, because it is within two standard deviations of the mean. OC. Significantly high, because it is more than two standard deviations above the mean. O D. It is impossible to determine with the information given.
