40. Although there is some controversy around the precise average body temperature of adults, new data suggest that the mean is 98.2° with a standard deviation of 0.6° and has a bell-shaped distribution. a. According to this distribution, approximately what percentage of body temperatures are between 97⁰° and 99.4°? b. Approximately what percentage of temperatures are greater than 98.8°2 c. Approximately what percentage of temperatures are no more than 98.2°?

2. Human body temperatures are normally distributed with a mean of 98.20°F and a standard deviation of .62F °. Find the temperature that separates the top 7% from the bottom 93%. Round to the nearest hundredth of a degree.

Suppose the durations of human pregnancies follow a mound-shaped distribution with a mean of 266 days and a standard deviation of 18 days. a. Approximately what percentage of human pregnancies last between 248 and 284 days?  b. Between what two values will the durations of 95% of all human pregnancies fall? Answer in days

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 72.6 Mbps. The complete list of 50 data speeds has a mean of x=18.29 Mbps and a standard deviation of s=19.75 Mbps.   a. What is the difference between​ carrier's highest data speed and the mean of all 50 data​ speeds? b. How many standard deviations is that​ [the difference found in part​ (a)]? c. Convert the​ carrier's highest data speed to a z score. d. If we consider data speeds that convert to z scores between −2 and 2 to be neither significantly low nor significantly​ high, is the​ carrier's highest data speed​ significant?       Question content area bottom Part 1 a. The difference is 54.3154.31 Mbps. ​(Type an integer or a decimal. Do not​ round.) Part 2 b. The difference is enter your response here standard deviations. ​(Round to two decimal places as​ needed.)

Consider the data from the Anthropology 105 class.  The mean for women is 64.33 in and the standard deviation is 2.64 in. The average height of men in the US is approximately 5ft 10in. What proportion of women represented here are shorter than the average man?

Let x denote thumb length for a female specimen.   a. Find the standardized version of x. b. Determine and interpret the​ z-scores for thumb lengths of 10.3 mm and 7.1 mm. Round your answers to two decimal places.   a. Find the standardized version of x.   z=enter your response here

Use the following information for the question. The average travel time to work for a person living and working in Kokomo, Indiana is 17 minutes. Suppose the standard deviation of travel time to work is 4.5 minutes and the distribution of travel time is approximately normally distributed.Which of these statements is asking for a measurement (i. e. is an inverse normal question)?   A.What percentage of people living and working in Kokomo have a travel time to work that is between thirteen and fifteen minutes?   B.If 15% of people living and working in Kokomo have travel time to work that is below a certain number of minutes, how many minutes would that be?

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 73.7 Mbps. The complete list of 50 data speeds has a mean of x = 16.05 Mbps and a standard deviation of s = 17.75 Mbps. a. What is the difference between carrier's highest data speed and the mean of all 50 data speeds? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the carrier's highest data speed to a z score. d. If we consider data speeds that convert to z scores between -2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant? ..... a.
