A student group started a class project that needs to compare the ages of male and female prisoners. The following are the ages (in years) of randomly selected male and female prisoners in a certain federal prison. Is there sufficient evidence to conclude the difference in the means (average age) is statistically significant? use 5% (α = 0.05) significance level.

Male prisoners: 29, 25, 17, 36, 41, 25, 32, 29, 38, 34, 24, 27, 29.

Female prisners: 41, 41, 37, 29, 30, 38, 39, 10, 29, 55, 29.

a) Write the null hypothesis and alternative hypothesis to test the above claim.

b) What is the value of the test statistic?

c) What is the degrees of freedom of the t distribution of the test statistic?

d) What is the p-value?

A random sample 11 student cars (group 1) were found to have ages with a mean of 7 years and a standard deviation of 3.4 years, while second, independent random sample of 10 faculty cars (group 2) were found to have ages with a mean of 5.2 years and a standard deviation of 3.5 years. You may assume that car ages for both groups are approximately normally distributed and that the two population variances are equal. 1. Use a 0.01...

A student needs 62.5 g of zinc sulfide, a white pigment, for an art project. He can synthesize it using the reaction: Na2S (aq) + Zn(NO3)2 (aq) = ZnS(s) + NaNO3 (aq) (not balanced) (78.04) (189.4) (97.44) (85.00) How many grams of zinc nitrate will he need if the percent yield of zinc sulfide is 85.0 %?
