The manager went over the sales of mobile phones at the store and found that the mean sale was 45, with a standard deviation of
d1i1m1o1n [39]

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}

∴ z=\frac{7}{4}

∴ z = 1.75

The z-score of the sale of mobile phones on that day is 1.75
