Assume that a simple random sample has been selected from a normally distributed population and test the given claim. identify the null and alternative hypotheses, test statistic, p-value, critical value(s). and state the final conclusion that addresses the original claim. a safety administration conducted crash tests of child booster seats for cars. listed below are results from those tests, with the measurements given in hie (standard head injury condition units). the safety requirement is that the hic measurement should be less than 1000 hic. use a 0.05 significance level to test the claim that the sample is from a population with a mean less than 1000 hic. do the results suggest that all of the child booster seats meet the specified requirement? 697 759 1266 621 569 432
what are the hypotheses
identify the test statistic
identify the p-value.
the critical value(s) is(are)
state the final conclusion that addressses the original claim
what do the results suggest about the child booster seats eeting the specific requirement?

An oil exploration company currently has two active projects, one in asia and the other in europe. let a be the event that the asian project is successful and b be the event that the european project is successful. suppose that a and b are independent events with p(a) = 0.2 and p(b) = 0.8. (a) if the asian project is not successful, what is the probability that the european project is also not successful? (b) what is the probability that at least one of the two projects will be successful? (c) given that at least one of the two projects is successful, what is the probability that only the asian project is successful? (round your answer to three decimal places.)
