Answer:
The testing statistic is -2.237
Step-by-step explanation:
Test statistic (z) = (sample mean - population mean) ÷ (population standard deviation/√n)
sample mean = 6.3 ounces
population mean = 6.4 ounces
population standard deviation = 0.2 ounces
n (sample size) = 20
z = (6.3 - 6.4) ÷ (0.2/√20) = -0.1 ÷ 0.0447 = -2.237
