quizzes/2866979/take(9) The combination of a bike lock consists of 5 digits, where the the first two digitscannot be the same, there's no restriction on the other digits. How many possibilitesare there? Remember that there are 10 digits.(10) A (very bad) factory produces plastic bags such that 30% of the plastic bags produccdarc defective and 70% are good. A sample of 5 plastic bags is selected at random.(a) What is the probability that all 5 bags selected are defective?(b) What is the probability that at least 4 of the 5 bags selected are defective?

We’ll answer the first question since the exact one wasn’t specified. Please submit a new question…

Suppose you rolled a fair six-sided die a few times and recorded the results. (You would have a collection of numbers 1-6.) Now, suppose you wanted to average these numbers. What value would you expect? If the die was rolled 6 times and the results were: 1, 4, 2, 2, 3, 2, then the average of this sample of rolls would be 2.333. This experiment could be peformed again: 6, 5, 2, 1, 1, 4. Now, the average of this sample is 3.167. Obviously, these small samples have a lot of variation in them; however, is there a way to calculate the expected average? If we were to construct a very large sample, rolling this die 1 million times, what would the expected value (mean) be? Luckily, the rules of probability allows us to do this calculation without actually having to roll the die 1 million times! Below, you will find a probability table where all of the possible outcomes from the die are listed. The first column contains the possible outcomes on the die, the second column contains the…
Three different people take simple random samples of size 400 from a box of 100,000 tickets, each marked 0 or 1, without knowing its contents. The number of 1's in the first sample is 72. In the second, it is 84. In the third, it is 98. Each person estimates the SE by the bootstrap method. Options: 0.081, 0.02, 0.245, 0.18, 0.384, 0.022, 0.43, 0.077, 0.407, 0.21, 0.086, 0.019 The first person estimates the percentage of 1's in the box as, _________ and figures this estimate is likely to be off by give or take _______ The second person estimates the percentage of 1's in the box as, _________ and figures this estimate is likely to be off by give or take ________ The third person estimates the percentage of 1's in the box as, _________ and figures this estimate is likely to be off by give or take __________ Fill in the blanks with the options given

Can you please explain and help me do this since I am allowed to on a ti84? Thank you. ex:You are testing the claim that the proportion of men who own cats is larger than the proportion of women who own cats.You sample 90 men, and 20% own cats.You sample 170 women, and 90% own cats.Find the proportion of the pooled samples, (pcpc), as a decimal, rounded to two decimal places.
