HUMOR In an article in the Journal of Advertising, Weinberger and Spotts compare the use of humor in television ads in the US and in the UK. Suppose that independent random samples of television ads are taken in both countries. A random sample of 400 TV ads in the UK reveals that 142 use humor, while a random sample of 500 TV ads in the US reveals that 122 use humor. 1. Set up Ho and Ha needed to determine whether the proportion of ads using humor in the UK differs from the proportion of ads using humor in the US. 10 Points 2. Test the hypotheses for alpha (level of significance) values of .10, .05, .01, and .001. What can you conclude in each case? 20 Points GOLF Golf Ball Durability Test Results Alpha BestCentury Divot 281270218364 220334244302 274307225325 242290273337 251331249355 In order to compare the durability of four different brands of golf balls (ALPHA, BEST, CENTURY, and DIVOT), the National Golf Association randomly selects five balls of each brand and places each ball into a machine that exerts the force produced by a 250-yard drive. The number of simulated drives needed to crack or chip each ball is recorded. Test for statistically significant differences between the 4 means, µALPHA, µBEST, µCENTURY, and µDIVOT at alpha levels of .05 and .01. 30 points

HUMOR
        Given that
        Number of TV ads in the UK(n1)                        400
        Numeber of TV ads Use Humor(x1)                         142
        Number of TV ads in the US(n2)                        500
        Numebe of TV ads Use Humor(x2)                        122
        Proportion of TV ads who use Humor in UK(p1)                         0.355
        Proportion of TV ads who use Humor in US(p2)                         0.244
        Pooled Proportion( P)                        0.2933
        Standard Error (SE)                         0.0305417747
    a)
        Null hypothesis(H0):The proportion of ads using humor in the UK is not signfifcatly different from the proportion of ads using
humor in the US.
        H0: P1 =P2
        Alternative hypothesis(H1):The proportion of ads using humor in the UK is not signfifcatly different from the proportion of ads using
humor in the US.
        H1: P1 ≠P2
    b)
                                3.63
        Test statistic value of Z
                                0.0003
        P-value
                                0.10
        Level of significance value(α)
        Decision:    Here we observe that p-value(0.0003) is less than level of signficance value(0.10). So we reject the null hypothesis(H0)
        Concusion:    Therefore we cocnlude that there is a sufficient evidence to support that The proportion of ads using humor in the UK is signfifcatly different from the proportion of ads using
humor in the US.
        Level of significance value(α)                        0.05
        Decision:    Here we observe that p-value(0.0003) is less than level of signficance value(0.05). So we reject the null hypothesis(H0)
        Concusion:    Therefore we cocnlude that there is a sufficient evidence to support that The proportion of ads using humor in the UK is signfifcatly different from the...
