Answer

Rounding to two decimal places, we get the final answer: $41.93$

Steps

Step 1 ：We are given a table with a missing value 'x', and we are provided with the z-score, the mean (μ), and the standard deviation (σ). The table is as follows: $Unknown environment 'tabular'$

Step 2 ：We can use the formula for finding a z-score to determine the missing value 'x'. The formula is: $z = \frac{x - μ}{σ}$

Step 3 ：We can rearrange the formula to solve for 'x': $x = z σ + μ$

Step 4 ：Substitute the given values into the formula: $x = 1.86 \times 3.94 + 34.6$

Step 5 ：Solving the equation gives us the value of 'x': $x = 41.9284$

Step 6 ：Rounding to two decimal places, we get the final answer: $41.93$
