Mean alcohol expenditures for ucm students

Reference no: EM1314032

Monthly expenditures on alcohol were gathered for 50 Central students and for 50 students from Southwest Baptist University. These figures are given below and are in dollars ($'s). Assuming that the variances for both schools' data are the same, use Excel and the data to test whether the mean alcohol expenditures for UCM students is equal to that of SBU students using a 1 % level of significance. Will your answer change for α = 0.02? Show.

UCM Students:
198	295	403	105	214	76	188	295	198	100
180	10	200	203	410	192	372	394	297	108
356	103	94	27	404	377	383	387	390	63
307	207	366	198	105	198	191	293	425	210
255	393	226	500	320	182	281	12	283	402

SBU Students:
136	144	0	96	202	2	72	39	392	109
151	363	72	175	177	357	160	68	7	72
206	189	98	21	35	262	178	20	10	303
0	62	105	165	240	182	178	101	306	66
135	91	25	10	310	281	30	291	397	199

Finally, an SBU administrator claims that their students spend no more than $150 on average on alcohol (the local city council claims they spend much more!). Is there enough evidence to support either the administrator's or council's claim? (Use a one-tailed test and a 5% level of significance.)
