This came from a random sample of 35students. Use this data to test the claim that retaking the SATincreases the score on average by more than 25 points. Test thisclaim at the 0.10 significance level.
(a) The claim is that the mean difference (x - y)is greater than 25 (μd > 25). Whattype of test is this?This is a two-tailed test.This is a left-tailedtest.    This is a right-tailed test. (b) What is the test statistic? Round your answer to 2decimal places. td =
(c) Use software to get the P-value of the test statistic.Round to 4 decimal places. P-value =
(d) What is the conclusion regarding the null hypothesis?reject H0fail to rejectH0    (e) Choose the appropriate concluding statement.The data supports the claim that retaking the SAT increases thescore on average by more than 25 points.There is not enough data tosupport the claim that retaking the SAT increases the score onaverage by more than 25 points.    We rejectthe claim that retaking the SAT increases the score on average bymore than 25 points.We have proven that retaking the SAT increasesthe score on average by more than 25 points.     |     Senior Score (x) | Junior Score (y) | (x - y) | 1265 | 1238 | 27 | 1150 | 1110 | 40 | 1225 | 1174 | 51 | 1081 | 1070 | 11 | 1264 | 1224 | 40 | 1220 | 1205 | 15 | 1108 | 1102 | 6 | 1321 | 1274 | 47 | 1317 | 1264 | 53 | 1177 | 1167 | 10 | 1102 | 1063 | 39 | 1291 | 1252 | 39 | 1235 | 1195 | 40 | 1091 | 1060 | 31 | 1097 | 1062 | 35 | 1101 | 1073 | 28 | 1278 | 1222 | 56 | 1214 | 1187 | 27 | 1100 | 1061 | 39 | 1101 | 1066 | 35 | 1240 | 1217 | 23 | 1216 | 1183 | 33 | 1120 | 1091 | 29 | 1295 | 1273 | 22 | 1131 | 1095 | 36 | 1293 | 1263 | 30 | 1174 | 1122 | 52 | 1212 | 1193 | 19 | 1124 | 1116 | 8 | 1114 | 1084 | 30 | 1109 | 1087 | 22 | 1177 | 1134 | 43 | 1151 | 1076 | 75 | 1289 | 1267 | 22 | 1061 | 1064 | -3 | |
