If 1 adult female is randomly selected, find the probability that her pulse rate is less than 79 beats per minute. (round decimal to four places as needed). B. If 16 adult females are randomly selected, find the probability that they have pulse rates with a mean less than 79 beats per minute. (round to four decimal places as needed) C. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30?
The mean score on a driving exam for a group of driver's education students is 88 points, with a standard deviation of 3 points. Apply Chebychev's Theorem to the data using k=2. Interpret the results. At least ___________%of the exam scores fall between_________and _________.
Assume that the readings on a batch of thermometers are normally distributed with a mean of 25°C and a standard deviation of 0.4°C. A single thermometer is randomly selected and tested.If 0.4% of the thermometers are rejected because they have readings that are too high and another 0.4% are rejected because they have readings that are too low, find the two readings that are cutoff values separating the rejected thermometers from the others.interval of acceptable thermometer readings = °C Note: Type your interval in parenthesis to at least 3 decimal places. For example, an interval from 3.123 to 8.123 would be typed in as (3.123,8.123).
