The z-score of the sale of mobile phones on that day is 1.75
Step-by-step explanation:
The formula of z-score is z = (x - μ)/σ, where:
- x is the score
- μ is the mean
- σ is the standard deviation
∵ The mean sale was 45
∴ μ = 45
∵ The standard deviation was 4
∴ σ = 4
∵ 52 mobile phones were sold on a particular day
∴ x = 52
To find z-score of the sale of mobile phones on that day substitute the values of x, μ, and σ in the formula of z-score
∵ ![z=\frac{52-45}{4}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B52-45%7D%7B4%7D)
∴ ![z=\frac{7}{4}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B7%7D%7B4%7D)
∴ z = 1.75
The z-score of the sale of mobile phones on that day is 1.75
