Armando thinks that he has a special relationship with the number 1. In particular, Armando thinks that he would roll a 1 with a fair 6-sided die more often than you'd expect by chance alone. Suppose p is the true proportion of the time Armando will roll a 1. a) State the null and alternative hypotheses for testing Armando's claim. (Type the symbol "p" for the population proportion, whichever symbols you need of <, ">, =', "not =' and express any values as a fraction e.g.p= 1/3) Ho = p=1/6 H = p>1/6 (b) Now suppose Armando makes n = 30 rolls, and a 1 comes up 6 times out of the 30 rolls. Determine the P-value of the test, giving your answer to 4 decimal places. Please use 3 decimal places in your test statistic when finding the P-value P-value = 0.31136 Does this cent level that Armando rolls a 1 more often than you'd expect?

Hi there,  I missed last week's lecture and am really struggling to complete this week's homework. Below are the questions and instructions provided. Thanks in advance for your help!   General instructions • All numerical answers that required decimal places must contain 2 and only 2 decimal places. • Number your answers exactly as the questions are numbered. • Submit only your numbered answers to the questions nothing more. Scenario 1 – answer questions 1 – 12 based on this scenario Todd just got back his exam grades in three classes. In biology the class mean was 75.80 with a standard deviation of 5.15, Todd got an 84.00. In political science the class mean was 84.00 with a standard deviation of 5.50, Todd got an 84.00. In economics the class mean was 87.50 with a standard deviation of 5.60, Todd got a 84.00. 1. What is Todd’s z score for biology? 2. What is Todd’s z score for political science? 3. What is Todd’s z score for economics? 4. Which class showed the highest variability in…

can you do step 4 without using excel?  I have to use a formula to find p value on a test on wednesday.

is there a shorter way to do this where you don't get decimals in your answer?
