Only 19% of registered voters voted in the last election. Will voter participation increase for the upcoming election? Of the 339 randomly selected registered voters surveyed, 75 of them will vote in the upcoming election. What can be concluded at the αα = 0.05 level of significance? The p-value = (Please show your answer to 4 decimal places.) The p-value is ? ≤ > αα Based on this, we should Select an answer reject accept fail to reject the null hypothesis. Thus, the final conclusion is that ... A) The data suggest the population proportion is not significantly higher than 19% at αα = 0.05, so there is statistically insignificant evidence to conclude that the percentage of registered voters who will vote in the upcoming election will be higher than 19%. B) The data suggest the population proportion is not significantly higher than 19% at αα = 0.05, so there is statistically significant evidence to conclude that the percentage of registered voters who will vote in the…

Please do this short answer question correctly We are going to roll 5 independent dice (like playing Yahtzee - but we will only roll once). The sum of the values of the dice can range anywhere from 5 (a roll of all 5 dice being a 1) to 30 (a roll of all 5 dice being a 6). I have determined that (to the 6th decimal) P(sum of values of the dice ≥ 8) = .997299. (i) Determine the P(sum of values of the dice ≤ 7) (to the 6th decimal). (ii) Provide a brief explanation as to the reason why your answer is correct.
