Question

A Harris Corporation/University of Florida study was undertaken to determinewhether a manufacturing process recently created is acceptable. A good process isconsidered to be one with voltage readings of at least 9.2 volts (with larger readingsbeing better than smaller readings) occurring at least 95% of the time. The databelow contains voltage readings for 30 production runs.

o9.19, 9.63, 10.10, 9.70, 10.09, 9.60, 10.05, 10.12, 9.49, 9.37, 10.01, 8.82,9.43, 10.03, 9.85, 9.27, 8.83, 9.39, 9.48, 9.64, 8.82, 8.65, 8.51, 9.14, 9.75,8.78, 9.35, 9.54, 9.36, 8.68
oConstruct a relative frequency histogram for the voltage readings using SPSS.
oDo you think the manufacturing process is acceptable? Explain in one sentence.

Answer 1

Check the explanation

Explanation:

Kindly check the attached images for the beginning of the solution to the question

b) P(X > 9.2) is less than 95%

there is signfiicant proportion of readings which are less than 9.2

hence manufacturing process is not acceptable
