For each of the following situations determine the p-value that goes along with Z. a. Z = 2.12‚ two-sided test b. Z = 4.55‚ two-sided test c. Z = -1.40‚ lower-tail test 2. Suppose Z = 1.92.Which has a smaller p-value‚ the upper-tail test or the two-sided test? From this‚ is it more likely to have a result that is

statistical test did not support the hypothesis. The statistical test proves that the null hypothesis can be accepted regarding temperature impacting weight. However‚ we accept the hypothesis regarding conductivity. The test shows that the conductivity of a cell submerged in a solution can be altered with changes in temperature as the independent variable. However‚ the test shows that we accept the null hypothesis for weight change because weight is not impacted by temperature. The statistical test used
