- An engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such that it would produce a mean pressure of 7.4 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 190 engines and the mean pressure was 7.5 pounds/square inch. Assume the standard deviation is known to be 0.9. A level of significance of 0.1 will be used. Determine the decision rule. Enter the decision rule. 画 Tables E Keypad Answer How to enter your answer Keyboard Shortcuts Reject Ho if z > | Submit Answer O 2020 Hawkes Learning MacBook Air 888 DII esc F3 F4 FS F7 23 $ & 1 2 3 4 6 8 { Q W E R Y P D F G H J K ?

A random sample of 34 new homes indicated that the mean cost was $120.61and the standard deviation was $17. Can it be concluded that the mean cost differs from $117.91, using the 0.10level of significance? Use the P-value method. Use a graphing calculator. (b) Find the P-value.
