Suppose that the neighboring cities of Tweed and Ledee are long-term rivals. Neal, who was born and raised in Tweed, is confident that Tweed residents are more concerned about the environment than the residents of Ledee. He knows that the average electricity consumption of Tweed households last February was 654.32 kWh and decides to test if Ledee residents used more electricity that month, on average. He collects data from 45 Ledee households and calculates the average electricity consumption to be 687.81 kWh with a standard deviation of 117.17 kWh. There are no outliers in his sample data. Neal does not know the population standard deviation nor the population distribution. He uses a one-sample t-test with a significance level of a = 0.05 to test the null hypothesis, Ho: µ = 654.32, against the alternative hypothesis, H1:µ > 654.32, where µ is the average electricity consumption of Ledee households last February. Neal calculates a t-statistic of 1.917 and a P-value of 0.031. Based on these results, complete the following sentences to state the decision and conclusion of the test. Neal's decision is to the (P=0.031). There is evidence to the hypothesis that the average electricity consumption of iS *....... 1.......

Suppose that the neighboring cities of Tweed and Ledee are long-term rivals. Neal, who was born and raised in Tweed, is
confident that Tweed residents are more concerned about the environment than the residents of Ledee. He knows that the
average electricity consumption of Tweed households last February was 654.32 kWh and decides to test if Ledee residents
used more electricity that month, on average. He collects data from 45 Ledee households and calculates the average
electricity consumption to be 687.81 kWh with a standard deviation of 117.17 kWh. There are no outliers in his
sample data.
Neal does not know the population standard deviation nor the population distribution. He uses a one-sample t-test with a
significance level of a = 0.05 to test the null hypothesis, Họ: µ = 654.32, against the alternative hypothesis,
H1:µ > 654.32, where u is the average electricity consumption of Ledee households last February. Neal calculates a
t-statistic of 1.917 and a P-value of 0.031.
