The contents of 3838 cans of coke have a mean of x¯¯¯=12.15x¯=12.15. assume the contents of cans of coke have a normal distribution with standard deviation of σ=0.12.σ=0.12. find the value of the test statistic zz for the claim that the population mean is μ=12.μ=12.

7.7055

Step-by-step explanation:

Given: Sample size :

Sample Mean :

Standard deviation :

Claim : The population mean is

We assume the contents of cans of Coke have a normal distribution .

We know that the test-static for population mean for larger sample is given by :-

Hence, the value of the test statistic z for the claim that the population mean is μ=12 is 7.7055.
