4.56 Nonstandard dice. Nonstandard dice can produce interesting distributions of outcomes. You have two balanced, six-sided dice. One is a standard die, with faces having one, two, three, four, five, and six spots. The other die has three faces with one spot and three faces with six spots. Find the probability distribution for the total number of spots Y on the up-faces when you roll these two dice.

The effect of graphite coating type (M, A, K, L) on light reading boxes will be investigated. Since these readings may change from day to day, the day effect was taken into the experiment as the block effect. Four coating types were tried in a random order each day. Obtained results are given below. According to this; Create the ANOVA table and interpret the results.
The U.S. Energy Information Administration claimed that U.S. residential customers used an average of 10,608 kilowatt hours (kWh) of electricity this year. A local power company believes that residents in their area use more electricity on average than EIA's reported average. To test their claim, the company chooses a random sample of 187 of their customers and calculates that these customers used an average of 10,737kWh of electricity last year. Assuming that the population standard deviation is 1220kWh, is there sufficient evidence to support the power company's claim at the 0.05 level of significance? Step 2 of 3 : Compute the value of the test statistic. Round your answer to two decimal places.

Q1: Exercises (Week 6) ‘Fit Camp’ is an intensive month-long programme of diet and exercise. Evidence shows that people who register for the programme and complete it see very satisfactory results. However, the regime is gruelling and experience dictates that 70% of people who register for the programme give up in the first 2 weeks. On a particular day, six people register for the programme. This can be thought of as a random sample. a) What is the probability that at least two of the six will give up in the first 2 weeks? b) What is the probability that at least two of the six will not give up in the first 2 weeks? Q2: Automobile Association records indicate that, on average, 3.2 breakdowns per day occur on a particular section of a UK motorway during the morning rush hour.

The Substance Abuse and Mental Health Services Administration (SAMHSA, 2017) estimates that 10.9% of the population of the United States age 18–24 had an episode of depression in the previous 12 months. Suppose a researcher takes a random sample of 225 United States adults aged 18–24. Determine the value of the sample proportion, p, such that 5% of samples of 225 United States adults age 18–24 are greater than p. You may find software or a z-table useful. Give your answer precise to three decimal places. p = II
