A student selects 49 batteries from a population with a mean mass value of 72: (uts). She measured a sample mean and obtained a value of 74±7.0 g (uts). Con one-independent z-test to determine whether mass values are different at significance level. Hint: Use the formula for paired t-test to obtain zcalc.

Question
A student selects 49 batteries from a population with a mean mass value of 72±7.0 g (uts). She measured a sample mean and obtained a value of 74±7.0 g (uts). Conduct a one-independent z-test to determine whether mass values are different at 0.05 significance level. Hint: Use the formula for paired t-test to obtain zcalc.
