Question

Identify the following:

a. x=_______

b. sx =_______

c. n =_______

d. n – 1 =_______

Short answer

Identify the following:

1. The$\text{sample mean waiting time was}1.5\text{hours, that is,}\overline{x}=1.5$
2. The sample standard deviation is 0.5
3. The total number n= 70
4. $n-1=69$
   

Step-by-step solution

Part (a) Step 1: Given Information 

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

Part (a) Step 2: Explanation

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.

Part (b) Step 1: Given Information

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

Part (b) Step 2: Explanation of (b)

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 .

Part (c) Step 1: Given Information

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

Part (c) Step 2: Explanation

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.

Part (d) Step 1: Given Information 

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

Part (d) Step 2: Explanation

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$
