-2.05
Step-by-step explanation:
From the given information,
Let consider
to represent the population mean
Therefore,
The null and alternative hypothesis can be stated as :
From the hypothesis , the alternative hypothesis is one tailed (left)
when the level of significance = 0.020, the Z- critical value can be determined from the standard normal distribution table
Hence, the Z-critical value at ∝ = 0.020 is -2.05
