Final answer:
To find the value of zα, use the standard normal distribution table or a calculator. In this case, α = 0.029. By looking up 0.029 in the table or using a calculator, we can find that zα is approximately -1.8808.
Step-by-step explanation:
To find the value of zα, we need to use the standard normal distribution table or a calculator. In this case, α = 0.029. We want to find the value of zα that corresponds to an area of 0.029 in the standard normal distribution curve. By looking up 0.029 in the table or using a calculator, we can find that zα is approximately -1.8808.
