Specifications for an aircraft bolt require that the ultimate tensile strength be at least 18 kN. It is known that 10% of the bolts have strengths less than 18.3 kN and that 5% of the bolts have strengths greater than 19.76 kN. It is also known that the strengths of these bolts are normally distributed.a. Find the mean and standard deviation of the strengthsb. What proportion of the bolts meet the strength specification?

Suppose a researcher is testing someone to see if he or she can tell Soda X from Soda Y, and the researcher is using 28 trials, half with Soda X and half with Soda Y. The null hypothesis is that the person is guessing. The alternative is one-sided, Upper H Subscript a: p 0greater than0.5. The person gets 17 right out of 28. The p-value comes out to be 0.129. Explain the meaning of the p-value.

Suppose a bowler claims that her bowling score is not equal to 150 points, on average. Several of her teammates do not believe her, so the bowler decides to do a hypothesis test, at a 5% significance level, to persuade them. She bowls 22 games. The mean score of the sample games is 157 points. The bowler knows from experience that the standard deviation for her bowling score is 18 points.
