##1a)
*Using the wt column within the mtcars data set, test the hypothesis that the mean weight is different from 3.00. Use an alpha level of .01*

##b
*Comparing different precise recipies for chocolate cake, a study was conducted to examine the weight in grams of flour in each recipe. A well known scientific cookbook claims that the true mean number of grams of flour to put in chocolate cake is 250 grams. A sample of 8 cake recipies was collected in the study and found that the sample mean and standard deviation were 230 and 10 respectively. Conduct a test to see if the true mean grams of flour is less than 250. Use an alpha level of .05*

Be sure that you type an explanation for the result of each test BELOW the chunk that you conducted the test in. Please in r studio codes solve them and thanks

*Using the am column of the mtcars data, test the hypothesis that the true proportion of automatic cars is .62 at the .01 significance level. Please not that am = 0 stands for automatic, while am = 1 stands for manual.* Please make sure you solve in R-studio. Solving without giving me R-codes will not help me. It would also help if you write a brief explanation of what you did. Thanks in advance!

Provide an original example where you perform a hypothesis test using the one-mean z-test. Provide within this part the following items: State the null hypothesis. State the alternative hypothesis test. State the chosen alpha level of significance. Use the critical value approach to determine whether to reject or fail to reject the null hypothesis. Use the p-value approach to determine whether to reject or fail to reject the null hypothesis. Discuss how a Type I or Type II error could...

Use the ”test.vs.grade” data and test the null hypothesis that the mean test score for the population is 70 against the alternative that it is greater than 70. Find a p-value and state your conclusion if α = 0.05. Repeat for the null hypothesis µ = 75. https://www.math.uh.edu/~charles/data/test.vs.grade.csv
