When rolled, two dice should come up to a sum of 8 at a rate of 13.89%. I roll two dice 100 times and get 11 sums of 8.
a) At the .01 level are the dice coming up at a statistically different % of 8 than expected? (p = .403)

Question 8. For finding p-values, there are two approaches - bootstrap or use a distribution for the test statistic under the null hypothesis (like standard normal, T, Chi-Square, F). Using the distribution approach requires some assumptions (such as normality, or approximate normality, of the population distribution, large sample sizes, etc.)
For the following testing scenarios, write down the assumptions that are needed
a. Testing of equality of proportions between two categorical variables - p1 and p2.
Ho: p1 = p2 vs H1: p1 /= p2. Sample size n1 and n2
b. Testing for equality of proportions between three categorical variables using the Chi-Square Goodness of Fit approach
Ho: p1 = p2 = p3 vs H1: at least one pair of pi's is not the same. Sample sizes n1, n2, n3. Total sample size n = n1+n2+n3
a. Testing of equality of population means between three populations using the ANOVA table.
Ho: mu1 = m2 = mu3 vs H1: not all population means are the same Sample size n1, n2, n3

A stock's current price on the London Stock Exchange is £8. There are two possible prices at the end of the year: £11 or £8. A call option to buy one share at £10 at the end of the year sells at £2. Suppose that you are told that a riskless portfolio can be created by selling 3 call options, buying 2 stocks today and borrowing £10 today.
(a) What is the risk free interest rate?
(b) Is the interest rate realistic in the UK? What values in the introduction of the question could explain such an interest rate?
