SHOW THE COMPLETE DETAILED EXPLANATION. 3. "Suppose that in the past, 74% of all adults favored capital punishment. Do we have a reason to believe that the proportion of adults

Mathematics and Probability Theory Question 3 (a) The number of calls at a call-centre on average is 5 in every minutes. Calculate the probability that at most 3 calls are received at the call-centre in the period of two minutes. (5 marks) (b) A message is sent through three possible routes with probabilities 0.3, 0.25 and 0.45, respectively. The

Use a normal approximation to find the probability of the indicated number of voters. In this case, assume that 148 eligible voters aged 18-24 are randomly selected. Suppose a previous study showed that among eligible voters aged 18-24, 22% of them voted. Probability that fewer than 38 voted CID The probability that fewer than 38 of 148 eligible

How much must you put in this CD now in order to have $3,000 for a home-entertainment center in 3 years. The present value that must be invested to get $3,000 after 3 years at an interest rate of

g. Assuming the population mean time of listening to radiom=95 minutes, is there sufficient evidence to conclude that the mean time listened to radio on Saturday is less than national average? Formulate the null and the alternative hypothesis and use both critical value and p-value approach to test this hypothesis at 5% level of significance. (no

A box contains six red pills and three blue pills. Morpheus selects one pill at random and gives it to Neo. He then selects another pill at random and gives it to Trinity. Compute your answers as probabilities to 4 decimal places (where possible). What is the probability that Neo was given a red pill? ___________________ Neo was given a red pill.

Question 5 The management of Madeira Manufacturing Company is considering the introduction of a new product. The fixed cost to begin the production of the product is $30,000. The variable cost for the product per unit is expected to be uniformly distributed between $16 and $24. The product will sell for $60 per unit. Demand for the product is

A study was done using a treatment group and a placebo group. The results are shown in the table. Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. Use a 0.10 signicance level for

Question 12 2 pts A research study has reported that there is a correlation of r = 0.58 between the eye color (brown, green, blue) of an elderly person and the age when the person has trouble with night vision. This indicates: O The DMV should consider eye color when re-instating driver's licenses to elderly people. 0 The researchers should do
