1. A manufacturer of AA batteries is testing a new longer lasting design. AA batteries typically have a charge of 3 volts. A sample of _30 prototype batteries are tested and found to have an average of 3.2 volts and a sample standard deviation of 0.2. Does this provide sufficient evidence that the mean voltage for the new design is different than 3? Use a significance level of 5% X: H (if Ho is true): Sx: o (sampling distribution): n: df (degrees of freedom): Ho: HA: a: t value (test statistic): p-value: Describe the results of your analysis
