Research Methods - Coursework Example Since the alternative is of non-equality, the rejection zones will be in both ends of the distribution. Therefore the test will be two tailed. The p-value is 0.01070 using a significance level of 0.05 The alternative hypothesis is that the true coefficient is positive. So the rejection zone is on the right tail of the distribution and thus the test is right tailed. The computed t-value is 2.598522> 1.682 = the critical one sided 5% t value. Therefore, we reject the null hypothesis at 5% level of significance. Therefore, the test provides evidence of the fact that secondary enrollment has a significant positive impact on the growth of GDP. H0:?7=0 H1:?7>0 using a significance level of 0.1 Similar to the test conducted above, the alternative hypothesis is that the coefficient is positive. Therefore, the test will be right tailed once more. The computed t-value =1.50471< 2.418 = the critical 1% t-value. So, we fail to reject the null hypothesis at the 1% level. This implies there is no evidence of private credit ratio having any observable impact on the dependent variable, growth of GDP. Evidently a contradiction arises between the conclusions obtained in (i) and (ii). In (i), the test fails to reject the null hypothesis that all the coefficients are jointly zero. But in (ii), the null hypothesis that the coefficient on the 1990 percapita GDP is zero is rejected. So, (ii) accepts the hypothesis (null in (ii), alternative in (i)) that is rejected by (i). To reconcile between these contradictions, it should be noted that tests of joint significance may fail to reject the null of joint insignificance if majority of the explanatory variables included are found to be insignificant. Usually, such cases arise if the basic assumptions of OLS are violated. Certainly if the presence of outliers skews the distribution of errors, such contradictions should be anticipated. 3. Primary recommendation for the finance minister on the basis of results From the results of the OLS mo del in part 1, we find that the coefficient on secondary enrolment as well as private credit ratio is positive. The coefficient for secondary enrolment is 0.254 and that for private credit ratio is 0.212. Thus, these are quite close to one another although that for private credit ratio is slightly lower. But critically, it should be noted that only the coefficient of secondary enrolment is statistically significant. So, only secondary enrolment among our variables of interest seems to have any effect on growth of GDP. There is no evidence that private credit has any impact on growth GDP. Thus my recommendation will be to invest the entire sum of $2 Billion on the policy measures that will increase the country’s rate of enrolment in secondary education. 4. Diagnostics This section will evaluate the validity of the standard assumptions of

Mozart Effect Essay Example | Topics and Well Written Essays - 1750 words

Mozart Effect - Essay Example But according to early studies the effect was temporary. These results do not bear directly on the Mozart effect in its narrow sense, but they have been cited as support for the more general thesis also. I also deeply believe that listening to Mozart's music may have an ever-lasting effect not only for many young students but also for many people of all ages. Mozart effect is most effective in telling us how emotionally humans are to using any aids to communicate when dealing with another sort of creature which is so unlike themselves in terms of experience, size, sensory capabilities, and emotional tendencies. Who would not want a pre-packaged solution with so impressive a name The effect in which exposure to classical music claims to enhance performance on intelligence tests has attained the status of an urban myth, a myth sustained by toy companies, parenting manuals writers, and technology gurus. As far as the today's requirements concert people demand that the arts should not be taught only as separate core subjects, but integrated throughout the curriculum, using examples of eighth notes, half notes, etc., writing poetry in reading and English classes, in science classes, and experiencing art, music and poetry in the geography, history and social studies being taught. The instrumental argument for the music is a great sales tool, if it does not lead to wild beliefs. It in no way detracts from the esthetic any more than the nutrition detracts from the food. For the music, making wild claims is just as bad as making wild claims for food or for anything else. Now I am suggesting some definitions of Mozart effect given by some famous experts. According to John Brue, "Scholastic ability, future career paths, and ability to form loving relationships have little basis in neuroscience of children will ultimately determine by Stories s that they experiences during their early years of life." According to Dr. Gordon Shaw, "We have this common internal neural language that we are born with and so if you can exploit that with the right stimuli then you are going to help the brain develop to do the things like reason." According to Dr. Frances Rauscher, "We exposed these animals in utero and then sixty days after birth to different types of auditory stimulation
