Question

For each statement, write the null and alternative hypotheses. State which hypothesis represents the claim. 17. Evaluate the limit, if it exists. Show work. lim→5 2−3−10 2−10

Answer 1

To evaluate the limit, substitute the value 5 for x in the expression and simplify the resulting expression. The limit is 7/15.

Step-by-step explanation:

For this problem, we are evaluating a limit. The given expression looks like:

limx→5 (2x-3)/(x^2-10)

To evaluate the limit, substitute the value 5 for x in the expression:

limx→5 (2(5)-3)/((5)^2-10)

Simplifying, we get:

limx→5 (10-3)/(25-10)

limx→5 7/15

So, the limit is 7/15.

Answer 2

Identify what you want to prove and you can test using ANOVA, Chi Square, F test ..... among many.

Step-by-step explanation:

Null and alternative hypothesis are always understood in terms of experiments.

In simple words,

null hypothesis = The results of your experiment are due to chance

alternative hypothesis = The results of your experiments are NOT due to chance

Therefore, identify what you want to prove and you can test using ANOVA, Chi Square, F test ..... among many.
