C10 Q14 V3 The dataset SUMMERSTUDENTS contains information from a random sample oi 44 students who took Statistics at MacEwan in the summer term. Your columns (variable) of interest are MUSICSTUDY (a column that records whether students listen to music while studying for an exam (no, yes)) and MAGE (a column that records student mother age). For education purposes assume that the two groups are two independent samples lrom a much larger normal population of statistics students and that the two populations have unequal variances. Use R to determine it, for a signicance level of 5%, there is signicant evidence that the mean age of student mothers in the yes group is lower than the mean age of student mothers in the no group. Choose the most correct (closest) answer. HINT. Be careful here. Recall that when doing a 2 independent samples t problem, R will calculate the numerator of the the test statistic by subtracting the sample mean of the yeses from the sample mean of the nos. 0 Your pvalue is 0007151, and you reject your null hypothesis. ' ' Your pvalue is 0.9928, and you fail to reject your null hypothesis. \" Your pvalue is 0.0143, and you fail to reject your null hypothesis. / ' Your pvalue is 0.0143, and you reject your null hypothesisStep by Step Solution
