(1) Using the binomial table, find the probability of getting 7 or more extreme than 7 in 8 trials, assuming a probability of.50 at each trial a. 0.0312 b. 0.0351 c. 0.0039 d. 0.0078 (2) A random sample of 8 Kean university students was drawn in order to determine if a film affected religious tolerance. Pre and post film ratings of religious tolerance were obtained. A higher number represents higher tolerance. The following data were obtained: Student Post film Pre Film 80 72 60 85 50 70 50 80 60 30 70 80 4. 37 67 87 (a). State the nondirectional alternative hypothesis. (b). State the null hypothesis. (c). Using the sign test, what is the probability of obtaining an outcome at least this extreme Gi.e, the outcome or a result even more extreme) if the null hypothesis is true? (d). Using a two-tailed alpha level of .05, what would one conclude? (e). What type of error may one be making in the conclusion in part d?Explanation / Answer
Providing first question answer in detailed
1) The following are binomial parameters and pmf
n = 8
p = 0.5, q = 0.5
pmf, p [x] = ncx px qn-x
Required probability
p [x >=7] = p [x = 7] + p [x = 8]
= 8c7 * 0.57 * 0.5 + 0.58
= 0.0039
So option C is correct
