A new laser-enhanced machining process has become available and the developer claims that the population proportion of screws which will pass the inspection will be more than .90, which would be an improvement over the current process. To test the validity of this claim, 900 screws produced by the new process are selected at random and the result will be used to make a decision as to whether or not the manufacturer should invest in the new process. What is the alternate hypothesis

The following details is missing from the question.

A machining process produces screws for which the population proportion of screws with defective threads is 0.10​ (10%)...

Step-by-step explanation:

Given

Required

Determine the alternate hypothesis

The initial given proportion represents the null hypothesis

i.e.

From the question, the new proportion is expected to pass the inspection with more than 0.90

More than, in inequalities means greater than.

So, the alternate hypothesis is:

answer: add the !

step-by-step explanation: then we will answer
