A computer manufacturer is interested in comparing assembly times for two keyboard assembly processes. Process 1 is an updated process hoped to bring adecrease in assembly time, while Process 2 is the standard process used for several years. Assembly times can vary considerably from worker to worker, andthe company decides to eliminate this effect by selecting 12 workers at random and timing each worker on each assembly process. Half of the workers arechosen at random to use Process 1 first, and the rest use Process 2 first. For each worker and each process, the assembly time (in minutes) is recorded, asshown in the table below.WorkerProcess 1Process 2Difference(Process 1 - Process 2)Send data to calculator1271 519358-22 -734569-2447574158699-1367072-27678686465- 19 -196392-291073731147120 - 174164 356Based on these data, can the company conclude, at the 0.10 level of significance, that the mean assembly time for Process 2 exceeds that of Process 1?Answer this question by performing a hypothesis test regarding μ (which is u with a letter "d" subscript), the population mean difference in assembly timesfor the two processes. Assume that this population of differences (Process 1 minus Process 2) is normally distributed.▷8AaK

A Hippogriff is a magical beast that had the front legs, wings, and head of a giant eagle and the body, hind legs and tail of horse. It is very similar to another magical creature, the Griffin, with the horse rear replacing the lion rear. A slightly different breed of Hippogriffs, living in the Rathlin Island-the northernmost point in Northern Ireland, has an initial population of No. From that initial population count, it grew to 705 individuals after 28 years. After 28 more years, the population of hippogriffs in Rathlin Island rose to 2764 individuals. If the carrying capacity of Rathlin Island for this particular specie is 3000 individuals, and calculate for the initial population and the growth rate constant of the said species.

Suppose that the captain of a ship that is in distress must send a total of eleven different signals in succession. The eleven signals com- prise of 4 blue light signals (B1, B2, B3 and B4), 4 purple light signals (P1, P2, P3 and P4) and 3 red light signals (R1, R2 and R3). He must send the signals one after another at 1 minute intervals. In how many different ways may the captain send the signals if the purple light signals are the first 4 signals and the red light signals are the last 3 signals? [Answer]

Sarah believes that completely cutting caffeine out of a person's diet will allow him or her more restful sleep at night. In fact, she believes that, on average, adults will have more than two additional nights of restful sleep in a four-week period after removing caffeine from their diets. She randomly selects 8 adults to help her test this theory. Each person is asked to consume two caffeinated beverages per day for 28 days, and then cut back to no caffeinated beverages for the following 28 days. During each period, the participants record the numbers of nights of restful sleep that they had. The following table gives the results of the study. Test Sarah's claim at the 0.05 level of significance assuming that the population distribution of the paired differences is approximately normal. Let the period before removing caffeine be Population 1 and let the period after removing caffeine be Population 2. Numbers of Nights of Restful Sleep in a Four-Week Period With Caffeine 24 22 24 20…

They have three assembly lines, “Razor,” “Blazer,” and “Tracer,” named after the particular dune buggy models produced on those lines. Each assembly line was originally designed using the same target production rate. However, over the years, various changes have been made to the lines. Accordingly, management wishes to determine whether the assembly lines are still operating at the same average hourly production rate.
