Question

**The data file reaction numbers that are listed below shows reaction distances in centimeters for the dominant hand for a random sample of 40 independently chosen college students. Smaller distances indicate quicker responses. Test the hypothesis that the population mean is not 10 cm using a significance level of 0.05.**-
**State the null and alternate hypotheses**.**Make a histogram and check normality. You should put a copy of your histogram.****Compute the appropriate t and p-value**.**What is your conclusion?**

Answer #1

Given the data set with t values in the first column and y
values in the second column, write a script file that:
-Curve fits the given data set with an appropriate polynomial
function
-Outputs the R2 value of the appropriate fit along
with the values of the polynomial order higher and lower (ex. If
you choose a 2nd order fit, display the R2
value for first, second, and third order fits.)
- Estimate the value of the data at...

The NaOH used in this lab should have been 0.1M, since you were
to make it as such (see Step 15 in lab document). Compare your
standardized average molarity of NaOH in this lab to 0.1M. How do
the values compare? How close was your NaOH dilution to actually
being 0.1M NaOH? Calculate your percent error against the average
standardized value from this lab. (You must show all work to
receive credit.)
step 15- Prepare an aliquot (fancy chemical term...

Using the New Call Center Data, provide a summary report for the
vice president including the following information
Using new call time and coded quality, develop a prediction
equation for new call time. Evaluate the model and discuss the
coefficient of determination, significance, and use the prediction
equation to predict a call time if there is a defect.
Evaluate whether the new call time meets customer specification.
As stated in a previous lesson, customers indicated they did not
want a...

please see experiment information below
(a) According to your experimental data, what volume of C6H8O7
represents the half-equivalence (a.k.a. half-neutralization) point
in this titration?
(b) What is the pH of the solution at the half-neutralization
point?

Using the two-sample hypothesis test comparing old call time to
new call time at a .05 level of significance, discuss the
hypothesis test assumptions and tests used. Provide the test
statistic and p-value in your response. Evaluate the
results of the hypothesis test with the scenario. Provide
recommendations for the vice president.
