Sagot :
The value of the area to the right of X > 6.7 calculated from the normal distribution principle is 0.334
Given the Parameters :
- Mean, μ = 6.4
- Standard deviation, σ = 0.7
- X = 6.7
Using the Zscore formula for a normal distribution :
- Zscore = (X - mean) / standard deviation
The Zscore, when X = 6.7
- Zscore = (6.7 - 6.4) / 0.7 = 0.4286
The area to the right of the distribution :
- P(Z > 0.4286) = 1 - P(Z < 0.4286)
Using a normal distribution table or calculator :
- P(Z > 0.4286) = 1 - 0.66589 = 0.334
Therefore, the probability value of P(X < 6.7) is
- P(Z > 0.4286) = 0.334
