Please find the critical value(s), the T value, and the P value

Transcribed Image Text:An engineer wants to know if producing metal bars using a new experimental treatment rather than the conventional treatment makes a difference in the tensile strength of the bars (the ability
to resist tearing when pulled lengthwise). At a = 0.10, answer parts (a) through (e). Assume the population variances are equal and the samples are random. If convenient, use technology to
solve the problem.
Treatment Tensile strengths (newtons per square millimeter) Q
Experimental 431 389 387 383 370 423 441
Conventional 440 357 380 414 406 420 373 406 374 365
(a) Identify the claim and state Ho and Ha
The claim is "The new treatment makes a difference
What are Ho and Ha?
The null hypothesis, Ho, is H₁ H₂. The alternative hypothesis, Ha, is Hy #H₂
Which hypothesis is the claim?
O The null hypothesis, Ho
The alternative hypothesis, Ha
in the tensile strength of the bars."
...
(b) Find the critical value(s) and identify the rejection region(s).
Enter the critical value(s) below.
