Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.The combined SAT scores for the students at a local high school are normally distributed with a mean of 1490 and a standard deviation of 298. The local college includes a minimum score of 2056 in its admission requirements. What percentage of students from this school earn scores that fail to satisfy the admission requirement?P(X < 2056) =In the past, a chemical company produced 880 pounds of a certain type of plastic per day. Now, using a newly developed and less expensive process, the mean daily yield of plastic for the first 50 days of production is 871 pounds; the standard deviation is 21 pounds. Do the data provide sufficient evidence to indicate that the mean daily yield for the new process is less than that of the old procedure?

- Suppose that the heart beat per minute (bpm) of adult males has a normal distribution with a mean of mu equals 68μ=68 bpm and a standard deviation of sigma equals 11.3σ=11.3 bpm. Instead of using 0.05 for identifying significant values, use the criteria that a value x is significantly high if P(x or greater)less than or equals≤0.01 and a value is significantly low if P(x or less)less than or equals≤0.01. Find the pulse rates for males that separate significant pulse rates from those that are not significant. Using these criteria, is a male pulse rate of 90 beats per minute significantly high?Assume a variable is normally distributed with a mean of 30 and standard deviation of 6.

P(X < 1555) = % Enter your answer as a percent accurate to 1 decimal place (do not enter the "%" sign). Answers obtained using exact z- scores or z-scores rounded to 3 decimal places are accepted.1. In the past, a chemical company produced 880 pounds of a certain type of plastic per day. Now, using a newly developed and less expensive process, the mean daily yield of plastic for the first 50 days of production is 871 pounds; the standard deviation is 21 pounds. Do the data provide sufficient evidence to indicate that the mean daily yield for the new process is less than that of the old procedure? (Use α=0.05) (d) Conclusion of the test above is Reject the null hypothesis and the mean daily yield for the new process is less than that of the old procedure. Reject the null hypothesis and the mean daily yield for the new process is not less than that of the old procedure. Do not reject the null hypothesis and the mean daily yield for the new process is less than that of the old procedure. Do not reject the null hypothesis and the mean daily yield for the new process is not less than that of the old procedure.The combined SAT scores for the students at a local high school are normally distributed with a mean of 1491 and a standard deviation of 299.
