The State Police are trying to crack down on speeding on a particular portion of the Massachusetts Turnpike. To aid in this pursuit, they have purchased a new radar gun that promises greater consistency and reliability. Specifically, the gun advertises ± one-mile-per-hour accuracy 75% of the time; that is, there is a 0.75 probability that the gun will detect a speeder, if the driver is actually speeding. Assume there is a 1% chance that the gun erroneously detects a speeder even when the driver is below the speed limit. Suppose that 72% of the drivers drive below the speed limit on this stretch of the Massachusetts Turnpike. a. What is the probability that the gun detects speeding and the driver was speeding? b. What is the probability that the gun detects speeding and the driver was not speeding? c. Suppose the police stop a driver because the gun detects speeding. What is the probability that the driver was actually driving below the speed limit?

wo cards are selected from a standard deck of 52 playing cards. The first card is not replaced before the second card is selected. Find the probability of selecting a nine and then selecting an eight. The probability of selecting a nine and then selecting an eight is nothing.

Answers

Answer:

0.6%

Step-by-step explanation:

We have a standard deck of 52 playing cards, which is made up of 13 cards of each type (hearts, diamonds, spades, clubs)

Therefore there are one nine hearts, one nine diamonds, one nine spades and one nine clubs, that is to say that in total there are 4. Therefore the probability of drawing a nine is:

4/52

In the second card it is the same, an eight, that is, there are 4 eight cards, but there is already one less card in the whole deck, since it is not replaced, therefore the probability is:

4/51

So the final probability would be:

(4/52) * (4/51) = 0.006

Which means that the probability of the event is 0.6%

Determine whether or not the given procedure results in a binomial distribution. For those that are not binomial, identify at least one requirement that is not satisfied.a) Treating 863 subjects with Lipitor (Atorvastatin) and recording whether there is a "yes" response when they are each asked if they experienced a headache.

d) Fifteen different Governors are randomly selected from the 50 Governors currently in office and the sex of each Governor is recorded.

Answers

Answer:

a

This procedure results in a binomial distribution

b

This procedure would not results in a binomial distribution

c

This procedure results in a binomial distribution

d

This procedure would not results in a binomial distribution

Step-by-step explanation:

A procedure must meet the following requirement in order for it to result in a binomial distribution

  •     The procedure trials must be independent
  •      Outcome of individual trials can be classified into two categories
  •       Success probability must remain the same in all trials
  •      The number of trials is fixed

Considering  the first procedure we can see that it satisfies the requirement of  above especially the requirement that the possible outcome of every trial is two

Considering the second procedure we see that would not results in a binomial distribution because the outcome of it trials cannot be classified into two categories

Considering  the third procedure we can see that it satisfies the requirement of  above especially the requirement that the trial must be independent

Considering the second procedure we see that would not results in a binomial distribution because there is no defined probability of success or failure

Answers

Answer:

  • 39, Obet is right

Step-by-step explanation:

  • I guess the = should be ÷ or else it doesn't make sense.

Simplify in steps considering the hierarchy of operations:

  • 3 + 6 × {(15 + 9) ÷ 3 - 2} =                  Parenthesis
  • 3 + 6 × {24 ÷ 3 - 2} =                         Parenthesis, division
  • 3 + 6 × {8 - 2} =                                 Parenthesis, subtraction
  • 3 + 6 × 6 =                                         Multiplication
  • 3 + 36 =                                             Addition
  • 39
