Asample of 106 healthy adults have a mean body temperature of 98.2, and a standard deviation of 0.62. construct a 99% confidence interval estimate of the mean body temperature of all healthy humans. group of answer choices ( 98.04, 98.36 ) ( 97.54, 97.95 ) ( 97.84, 98.12 ) ( 97.82, 98. 15 ) ( 97.95, 98.15 )

Step-by-step explanation:

Given : Sample size of healthy adults: n= 106

Degree of freedom = df =n-1 = 105

Sample mean body temperature  :

Sample standard deviation :

Significance level ;

∵ population standard deviation is unknown , so we use t- critical value.

Confidence interval for the population mean :

Using t-distribution table , we have

Critical value for df = 105 and =

A 99% confidence interval estimate of the mean body temperature of all healthy humans will be :

Hence, a 99% confidence interval estimate of the mean body temperature of all healthy humans =

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

won't that be plagrisim thought?
