Question

Two random samples (15 scores each) of data have been taken from the student "raw score" or true population with independent variable conditions: sample1 (water consumption) and sample2 (no water consumption) and given a memory assessment [test]. Experimental hypothesis: Depriving students of water for a week will affect memory ability. Next, compute the "n," sample mean, and estimated population variance and standard deviation using SPSS for both samples and conduct an independent two-sample t-test (with summary) to analyze the data/results with a two-tailed design (hypothesis above basically states difference = significant or no difference = non-significant). What is your conclusion? (t_obt compared to t_crit, accept, retain, reject the Statistical Hypotheses, and write results in the form of the equation

W= water NW= no water

sample 1(with memory scores) 33, 30, 33, 36, 31, 22, 40, 31 35, 34, 28, 28, 34, 33, 26,

Sample 2(nw memory scores) 16, 26, 30, 31, 32, 24, 28, 14, 36, 33, 28, 22, 28, 34, 22
