(16 points) You think that information printed in hard-to-read fonts {such as lls) will be remembered better than material printed in easy-to-read fonts (such as this) because the effort used to read the first type of font will result in deeper processing. You give subjects 90 seconds to read and study a list of information. You then give a test on the material 15 minutes later. The dependent variable is the score on the test. Here is a summary of the experiment: For some of the people (n=12l, the material is printed in an easy-to-read font. For some of the people (n=14), the material is printed in a hard-to-read font. You believe that the hard-to-read font group will score higher on the memory test than will the easy-to-read font group. You will use a T-TEST FOR INDEPENDENT SAMPLES to analyze the data. a. Complete the NONDIRECTIONAL null hypothesis. H 0' l-l'easytoread font __ l-J'hardtoread font b. Complete the NONDIRECTIONAL alternative hypothesis. H 1' l'l'easytoread font l'l'hardtoread font c. For the statistical analysis, the degrees of freedom is and the critical value oft (two-tailed with o = .05) is d. The scores on the test are below. Calculate the value of t. (There is more room on next page}. Remember you are using the t-test for independent samples.
