section : Independent-samples t-1est (Lh.1U) Before moving on to this, it's probably best to just close 5P5S, and then reopen 5PSS, in order to clear out everything from the previous problem. Loftus & Palmer [1974) conducted a study investigating the role of language on eyewitness memory. A group of college students were shown o video clip of an outomobile occident. One group was asked, \"About how fast were the cars going when they smashed into each other ?\" The other group was asked, \"About how fast were the cars going when they bumped eoch other?\" Below are some mode-up data, but they are similar to what Loftus & Polmer found. Here are the (made-up) data, measured in miles per hour: WORDING *Bum ped\" \"Smashed\" (Group 1) (Group 2) You will set up your SP55 dataset with two variables: WORDING and SPEED. Within the WORDING variable, you will label \"Bumped\" as group 1 and \"Smashed\" as group 2. Then you will test the hypothesis that participants with the \"smashed\" wording made significantly different speed estimates than participants with the \"bumped\" wording. . Open IBM 5P55. 2. Inthe first window that pops up, choose \"New Dataset,\" then click \"0K\". If the screen is cutting off and you can't see the \"OK" button, you can just hit the ENTER button on your keyboard. Go to Variable View (tab on bottom left of screen). Create a variable called \"WORDING\" in row 1, and a variable called \"SPEED\" in row 2. For the WORDING variable you just created, look at the column labeled \"Values\". Click on the first cell in that column. Either a box called \"Value labels\" should pop up, or you will just see a small blue box witha *.." appear in the cell that you just clicked on. If you small blue box appeared in the cell, click the small blue \".." box. NOW, no matter what, you should be looking at a pop-up box called \"Value labels\". 6. Inthe Value Labels box: a. Typein \"1\" for the Value, \"Bumped\" for the Label. Click \"Add\
