Consider the following null and alternative hypotheses: Null hypothesis: The average access to basic water services of people in rural and urban areas is equal. Alternative hypothesis: The average access to basic water services of people in rural areas is lower than that of people in urban areas. If the calculated test statistic is equal to -1.7756 and the critical value is 1.782 at a 5% level of significance, which of the following statements is true? We fail to reject the null hypothesis, suggesting that the average access to basic water services of people in rural and urban areas is equal. We fail to reject the null hypothesis, suggesting that we don't have enough evidence to say that the difference in the average access to basic water services between rural and urban areas is statistically significant. We reject the null hypothesis, suggesting that the average access to basic water services of people in rural areas is lower than that of people in urban areas. We cannot reject or fail to reject the null hypothesis based only on the information provided
