Question 9 bottles and measure their Not yet The liquid volume packaged in a bottle of A-brand orange juice follows a normal distribution, with a mean=u ml and standard deviation of 5 ml. We take a sample volumes. How many bottles do we have to sample so that we are 90% confident that the measured mean is within + 0.5 ml of the true mean? answered Round the result to the nearest integer. Marked out of 3.00 Note that from the 2-distribution table, we know. P(Z<= -1.645) = 5% Flag question P(Z<= -1.96) = 2.5% P(Z<= -1.28) - 10% Answer:
Question 10 Choose the CORRECT statement from the following Not yet answered Marked out of 3.00 On a single draw from a standard deck of cards, the probability of selecting a face card (only Jack Queen or King) is 3/52. O A car salesperson sells at most 3 cars per day. The probabilities for number of cars sold are as follows: p(O) = 0.19, P(1) = 0.34, p(2) = 0.43), p(3) = 0.29 and p(4) = -0.25. O The probability that it is cloudy tomorrow is 0.52 and that it is not cloudy tomorrow is also 0.52. On a single draw from a standard deck of cards, and given the condition that the selected card is red, the probability of selecting a heart card is 0.5. Flag question
