(b) Is there a significant difference in the average testosterone levels between obese and health weight adolescents? To answer this question, conduct an appropriate hypothesis test using the p-value method and a significance level of 5%. What can you conclude about these two groups of adolescents?

please send complete handwritten solution for Q6 part b

6. unknown whether this same pattern occurs in adolescents. A study was conducted that measured testosterone (in nmol/litres) in two independent random samples. The first sample included 10 obese adolescents, while the second sample included 6 adolescents with a healthy weight. Research has shown that obese adult males have lower levels of testosterone. However, it is Testosterone levels Obese Adolescents (n=10) Healthy Weight Adolescents (n=6) 0.04 0.16 0.36 0.10 0.31 0.60 0.30 0.31 0.60 0.20 0.19 0.94 0.10 0.73 0.94 0.39 Mean: 0.2550 Variance: 0.0061 Mean: 0.5483 Variance: 0.1389 (a) Based on this sample information, does it appear that the population variances are equal or unequal? Explain. (b) Is there a significant difference in the average testosterone levels between obese and health weight adolescents? To answer this question, conduct an appropriate hypothesis test using the p-value method and a significance level of 5%. What can you conclude about these two groups of adolescents? (c) What assumption must be true for the result in part (b) to be valid?
