Identify the following:

a. x=_______

b. sx =_______

c. n =_______

d. n – 1 =_______

Given that the sample mean was 1.5 hours with a sample standard deviation of 0.5 hoursand sample size 70

The sample mean is the average (or mean) value of a group of numbers drawn from a larger population of numbers, where "population" refers to all relevant data, whether or not it has been gathered.

Here, the sample means waiting time was 1.5 hours.

Given that the sample mean was 1.5 hours with a sample standard deviation of 0.5 hoursand sample size 70

The standard deviation is a measurement of a set of values' variation or dispersion.

According to the information, the sample standard deviation of the waiting time is 0.5 hours .

Given that the sample mean was 1.5 hours with a sample standard deviation of 0.5 hoursand sample size 70

The number of subjects included in a sample size is referred to as the sample size in market research. Here, the total number of patients surveyed by the investigation committee is 70.

Given that the sample mean was 1.5 hours with a sample standard deviation of 0.5 hoursand sample size 70

If the total [patient surveyed is 70 then$n-1=69$$\text{If the total patients surveyed is}70\text{, then the value of}n-1\text{is}69\text{, that is,}n-1=69$
