1. WHICH OF THE FOLLOWING STATEMENTS ARE CORRECT?
a. A normal distribution is any distribution that is not unusual. (Correct)
b. The graph of a normal distribution is bell-shaped. (Correct)
c. If a population has a normal distribution, the mean and the median are not equal.
d. The graph of a normal distribution is symmetric. (Correct)
Using the 68-95-99.7 rule:
Assume that a set of test scores is normally distributed with a mean of 100 and a standard deviation of 20. Use the 68-95-99.7 rule to find the following quantities:
Suggest you make a drawing and label first…
a. Percentage of scores less than 100 50%
b. Relative frequency of

Is the result unusual? Why or why not? What should you conclude?
Unusual. Because (101.00 – 98.2) / 0.62 = 4,5
In table 5-1, the z-score 4.5>3.5 so it is out from the normal distribution, so this body temperature is unusual.
f. What body temperature is the 95th percentile?
In table 5-1, 95th percentile is corresponds to a z-score 1.6 so
(x - 98.2) / 0.62 = 1.6
X = 99.19 °F or 99.2 °F
g. What body temperature is the 5th percentile?
In table 5-1, 5th percentile is corresponds to a z-score -1.6 so
(x - 98.2) / 0.62 = -1.6
x = 97.21 °F or 97.2 °F
h. Bellevue Hospital in New York City uses 100.6 °F as the lowest temperature considered to indicate a fever. What percentage of normal and healthy adults would be considered to have a fever? Does this percentage suggest that a cutoff of 100.6 °F is appropriate?
(100.6-98.2) / 0,62 = 3.87
In table 5-1, a z-score of 3.5 is corresponds to 99.98% as normal and healthy adults,
100 - 99.98 = 0.02 so 0.02% adults would be considered as having an abnormal body temperature, because we assume the body temperatures of healthy adults are normally distributed, then 0.02% / 2 = 0.01%.
So 0.01% of normal and healthy adults would be considered to have a fever
This percentage suggests that a cutoff of 100.6 °F is not appropriate. Because from table 5-1, the 99.98% is corresponds

1. Fill in the chart below. Use “+” if the patient’s vital sign is higher than normal, “−” if the sign is lower than normal, or “x” if the sign is normal. If you need to, use your text or another resource to determine normal values.
(2) Give that a sample of 25 had x = 75, and (x-x)² = 48 the mean and standard
5. Give the standard deviation for the mean and median column. Compare these and be sure to identify which has the least variability?
1. By hand, compute the mean, median, and mode for the following set of 40 reading scores:
1. Are any of the lab values in Table 1 out of normal range? Do you see some that are too high or too
Fry Brothers heating and Air Conditioning, Inc. employs Larry Clark and George Murnen to make service calls to repair furnaces and air conditioning units in homes. Tom Fry, the owner, would like to know whether there is a difference in the mean number of service calls they make per day. Assume the population standard deviation for Larry Clark is 1.05 calls per day and 1.23 calls per day for George Murnen. A random sample of 40 days last year showed that Larry Clark made an average of
Taking temperature is an integral part of patient care. It is one of the four vital signs and therefore is an essential piece of information to obtain so that an effective diagnosis can be made, for this reason the safety and accuracy of the measurement should be a high priority. Temperature is also considered an essential in hospital observation policy and Early Warning Score (EWS). A normal temperature ranges from 36.5oC to 37.2oC, however, normal body temperatures may vary due to many factors such as physical activity, room temperature and eating (Fuzy, 2003). The areas used for effective temperature measurement are as followed; mouth, rectum, armpit and ear, each require a different thermometer and method (choose well, nd.). Safely using a thermometer is not just about using the appropriate method but also about preventing the spread of
Temperature is very important temperature tells us the specific degree of hotness or coldness of the body. The hypothalamus triggers sweat glands and muscles incase the body needs to heat up and or cool down. The healthy average for temperature is somewhere between 97.8 and 99 degrees F. My heart rate was 98.6 which is in fact in between 97.8 and 99 degrees F. temperature is measured by a thermometer which can be many
Collected values representing temperature in kelvin(k) is a Ratio Data. Because in terms of kelvin temperature there is fixed intervals and as well as absolute zero. As there is absolute zero in kelvin temperature we can say that 5 degrees is half hot as compared to 10 degrees.
The proper yet least invasive route to perform the measurement of a core temperature in children has been an ongoing debate. Common methods or routes include axillary or in the armpit area, oral, rectal, tympanic, and temporal. Proper temperature measurement with an accurate result is important for diagnosis and treatment, especially in febrile children. False positive measurements can lead to extensive and unnecessary diagnostic testing while false negatives can lead to under treatment in a fragile population, which is why the
33.0 – 49.0 with a mean of 38.8±4.82. While in adults it ranged between 22.0 – 29.0 with a mean of 25.40±2.11 (Fig 3 A, B). ( (Table 1)
Vital signs: Temperature 98.7 Fahrenheit, BP 200/140 Pulse 80, Respiration 18, weight 345 IBS, BMI of 35.
