The contents of 3737 cans of Coke have a mean of x¯¯¯=12.1x¯=12.1 ounces and a standard deviation of 0.130.13 ounces. Assume the contents of cans of Coke have an approximately normal distribution. Find the value of the test statistic tt for the claim that the population mean is μ=12.

A random sample of 32 individuals was selected from the population of interest. The sample provided a mean of 19.5 and a standard deviation of 2.4. Find the p - value for the following null and alternative hypotheses.

(a)
H0:μH0:μ = 20.
Ha:μ<Ha:μ< 20.
The p - value is

(b)
H0:μH0:μ = 20.
Ha:μ≠Ha:μ≠ 20.
The p - value is

The contents of a sample of 26 cans of apple juice showed a standard deviation of 0.06 ounces. We are interested in testing to determine whether the variance of the population is significantly more than 0.003. At alpha of 0.10, we should Group of answer choices conclude that the variance of population is greater than 0.003 with a probability of 0.90 not reject the null hypothesis since the P-value is bigger than alpha. The population variance is not greater than...
