In a random sample of 40 men and women, he observes that men earn on average $3,700 and a standard deviation of $350, while in a sample of 37 women they earn on average $3,450 and a standard deviation of $320. Should the director reject the null hypothesis of \mu_1 = \mu_2 and accept the alternative hypothesis \mu_1 < \mu_2 at a significance level of 0.05?arrow_forwardPlease do not use chatgpt, avoid using it completely, because it does not do the math well, do it by hand step by step The director of a technical school wants to know who earns more, men or women.

- You have a sample of 4 pairs from two populations. The mean of the paired differences is 10 and the standard deviation of the differences is 5. Test the hypothesis, at the 5% level of significance, that the population means are the same. State your conclusion as a sentence including the test statistic and the critical value.arrow_forwardPlz help asap 6..arrow_forwardYou measure 24 backpacks' weights, and find they have a mean weight of 34 ounces. Assume the population standard deviation is 10 ounces. Based on this, construct a 90% confidence interval for the true population mean backpack weight. Give your answers as decimals, to two places ouncesarrow_forward
- Konstantinos participates in a bowling league each summer and again each autumn. In Summer 2021, his mean score for the year was 160. For the whole league, the mean score was 158 with a standard deviation of 6. For Autumn 2021, his mean score was 164. The mean for the entire Autumn league was 160 with a standard deviation of 4.5. In which league (summer or autumn) did Konstantinos perform better relative to his peers? please explain your response and round any numeric answers to three (3) decimal placesarrow_forwardThe Woodcock-Johnson Cognitive Ability test indicates that the average score is 95. The same group of 12th grade students (n = 72) in Columbus are tested and the sample mean is 110.1 and the sample standard deviation is 15.2. Do the scores provide good evidence that the mean IQ of this population is greater than 95? What is the p-value for this data what is your decision about the null hypothesis? reject or fail to reject?arrow_forward*please help me with this problem.I need to get it right to complete my homework.* In a test of the effectiveness of garlic for lowering cholesterol, 49 subjects were treated with garlic in a processed tablet form. Cholesterol levels were measured before and after the treatment. The changes (before- after) in their levels of LDL cholesterol (in mg/dL) have a mean of 3.9 and a standard deviation of 19.8. Construct a 99% confidence interval estimate of the mean net change in LDL cholesterol after garlic treatment. What does the confidence interval suggest about the effectiveness of garlic in reducing LDL cholesterol? What is the confidence interval estimate of the population mean muu? _mg/dL < muu< _mg/dLarrow_forward
