Final answer:

The x-value that is 1.8 standard deviations to the left of the mean is 0.5.

Step-by-step explanation:

To determine the x-value that is 1.8 standard deviations to the left of the mean, we can use the formula:

x = mean - (standard deviation * z-score)

Given that x ~ N(4.9,2.4), we substitute the values into the formula:

x = 4.9 - (2.4 * 1.8) = 0.5

Therefore, the x-value that is 1.8 standard deviations to the left of the mean is 0.5.
