What is the test statistic?test statistic = (Report answer accurate to 4 decimalplaces.)What is the p-value for this sample?p-value = (Report answer accurate to 4 decimalplaces.)The correct decision is to Select an answer reject thenull fail to reject the null .The correct summary would be: Select an answer There isnot enough evidence to support the claim There is not enoughevidence to reject the claim There is enough evidence tosupport the claim There is enough evidence to reject theclaim that the worksheet did improve the average quizscores.
