Blocks of concrete are tested for conformance tostrength specifications. The outcomes of the test areconsidered independent, and the probability of aconcrete block conforming to strength specificationsis 0.85a. What is the probability that exactly 5 concreteblocks are tested to obtain 3 concrete blocks thatconforms to strength specifications?b. Suppose one needs 4 consecutive concreteblocks conforming to strength specifications, whatis the probability that exactly 8 tests (for 8concrete blocks) are necessary?

A professional tennis player claims to get 90% of her second serves in. In a recent match, the player missed 5 of her first 20 second serves. Is this a surprising result if the player's claim is true? Assume that the player has a 0.10 probability of missing each second serve. We want to carry out a simulation to estimate the probability that she would miss 5 or more of her first 20 second serves. The dotplot displays the number of second serves missed by the player out of the first 20 second serves in 100 simulated matches. ▪………………………. ●●●●●●●●●●●●●● A●●●●●●●● …………….. 1 2 3 4 5 6 Number of missed serves in simulated match 7 Is there convincing evidence that the player misses more than 10% of her second serves? Why or why not? No, there is not convincing evidence that the player misses more than 10% of her second serves. Missing 5 out of 20 is better than expected. No, there is not convincing evidence that the player misses more than 10% of her second serves. Assuming the player makes…
