Question

the table below shows the number of vital - sign checks performed by nurses during their shifts. calculate the total number of checks performed and complete the \total\ row. then, determine the relative frequency for each number of checks, expressing the relative frequencies as simplified fractions in the corresponding column.
enter your answers as integers or fractions.
number of vital sign checks performed by nurses

number of checks	frequency	relative frequency
11	7
12	8
13	6
14	2
15	8
total	34

Explanation:

Step1: Recall relative - frequency formula

Relative frequency = $\frac{\text{Frequency of the class}}{\text{Total frequency}}$

Step2: Calculate relative frequency for 10 checks

Relative frequency for 10 checks = $\frac{3}{34}$

Step3: Calculate relative frequency for 11 checks

Relative frequency for 11 checks = $\frac{7}{34}$

Step4: Calculate relative frequency for 12 checks

Relative frequency for 12 checks = $\frac{8}{34}=\frac{4}{17}$

Step5: Calculate relative frequency for 13 checks

Relative frequency for 13 checks = $\frac{6}{34}=\frac{3}{17}$

Step6: Calculate relative frequency for 14 checks

Relative frequency for 14 checks = $\frac{2}{34}=\frac{1}{17}$

Step7: Calculate relative frequency for 15 checks

Relative frequency for 15 checks = $\frac{8}{34}=\frac{4}{17}$

Step8: Calculate relative frequency for total (should be 1)

Relative frequency for total = $\frac{34}{34} = 1$

Answer:

Number of Checks	Frequency	Relative Frequency
11	7	$\frac{7}{34}$
12	8	$\frac{4}{17}$
13	6	$\frac{3}{17}$
14	2	$\frac{1}{17}$
15	8	$\frac{4}{17}$
Total	34	1
