TABLE 10-6 Two Samples Each of Size 25 Are Taken from Independent

question 175

Short Answer

TABLE 10-6
Two samples each of size 25 are taken from independent populations assumed to be normally distributed with equal variances. The first sample has a mean of 35.5 and standard deviation of 3.0 while the second sample has a mean of 33.0 and standard deviation of 4.0.
-Referring to Table 10- 6, the p- value for a one- tailed test whose computed statistic is 2.50 (in the hypothesized direction) is between ____and ___ .

Definitions:

Acceptance Sampling

Acceptance Sampling is a statistical quality control method used to determine if a batch of goods meets predefined criteria, accepting or rejecting the batch based on sample testing.

Predetermined Standards

Benchmarks or criteria set in advance against which performance, quality, or other variables can be measured.

Operating Characteristic Curve

A graphical representation of a system's performance, showing the relationship between the acceptance level of a test and the true quality level.

Acceptance Sampling Plan

A statistical quality control method that determines whether to accept or reject a batch of products based on a sample, rather than testing the whole lot.
