Question

4.
Determine whether the following statements are true or false. No explanation is
required.
a) A paired t-test is used when the two samples cannot be treated as independent.
b) A 95% confidence interval for the ratio of two variances was calculated to be (0.589, 1.864).
A hypothesis test with significance level 0.05 would fail to reject the null hypothesis.
c) F(u,v) = F(v,u), where F(u,v) signifies an F distribution with u and v degrees of freedom.
d) When looking at population proportions, we can treat each sample as a binomial distribution
with n trials and probability of success po, where po is the hypothesized population proportion.
e) The F distribution is skewed left, unlike the normal and t distributions which are symmetric.

4. Find a 95% confidence interval for the difference of two means when you have independent samples, both of size 36, from two populations, in which the variances are not known to be equal. In this case, nị=36, s1²=6.1, the first sample mean is equal to 7.9; n2 =36, s2?=10.4, the second sample mean is equal to 9.1 Interpret the interval once you find it. Namely, can you conclude one mean is greater than the other mean and if so, which one?
The accounting department analyzes the variance of the weekly unit costs reported by two production departments. A sample of 16 cost reports for each of the two departments shows cost variances of 2.3 and 5.4, respectively. Is this sample sufficient to conclude that the two production departments differ in terms of unit cost variance? Use a = .10. a. State the null and alternative hypotheses. Ho: 0 12 equal to H : 0 1 ? not equal to 2 b. Calculate the value of the test statistic (to 2 decimals). c. The p-value is between .10 and .20 v d. What is your conclusion? Cannot conclude that the departments differ in terms of unit cost variance v
A study was undertaken to determine whether there was a significant weight (in lb) loss after one year course of therapy for diabetes, and whether the amount of weight (in lb) loss was related to initial weight. The following table gives the initial weight (x) and weight after one year of therapy (y) for 16 newly diagnosed adult diabetic patients. d. Which statistical test is appropriate to use on these data? e. Carry out the hypothesis test(s) in question in above d. Use α=0.01 (hypothesis, critical value, test statistic, conclusion) f. Are the means statistically different? g. Find the 99% confidence interval for the difference of the two means on weight. Interpret your finding
h) ii). Consider the results in Table 5. After running the regression, we test whether the coefficients of the variables hhsize1 and hhsize2 are equal at 5% significance level. The value of the F-statistic is 26.32. Note that the sample size is 1,593. What is the outcome of the test? i). Do you think the regression in Table 5 suffers from omitted variable bias? If yes, which additional variables would you include to control for omitted variable bias?

A researcher obtained the following for the 95% confidence interval for Pearson's correlation. [-0.05, 0.72] For a sample size of 20, based on r=0.40 Choose the correct statement a) 95% of sample correlations will fall between -0.05 and 0.72. We can therefore conclude that the correlation in the population differs significantly from zero. b) We are 95% confident that the correlation in the population is between -0.05 and 0.72. However this is based only on one sample and therefore it is inconclusive whether the population correlation differs significantly from zero. c) We are 95% confident that the correlation in the population is between -.05 and 0.72.. We can therefore conclude that the correlation in the population does differ signifcantly from zero. d) We are 95% confident that the correlation in the population is between -.05 and 0.72.. We can therefore conclude that the correlation in the population does not differ signifcantly from zero.
Bob selects independent random samples from wo populations and obtains the values p1 0.700 and p2 = 0.500. He constructs the 95% confidence interval for p1 – P2 and gets: 0.200 + 1.96(0.048) = 0.200 ± 0.094. Note that 0.048 is called the estimated standard error of p1 – p2 (the ESE of the estimate). Tom wants to estimate the mean of the success ates: Pi + P2 2 (a) Calculate Tom's point estimate. (b) Given that the estimated standard er- ror of (pi + P2)/2 is 0.024, calculate the 95% confidence interval estimate of (pi + P2)/2. Hint: The answer has our usual form: Pt. est. ±1.96 × ESE of the estimate. Carl selects one random sample from a popu- ation and calculates three confidence intervals for p. His intervals are below. A C p+0.080 p±0.040 p± 0.072 Match each confidence interval to its level, with evels chosen from: 80%, 90%, 95%, 98%, and 99%. Note: Clearly, two of these levels will not be used.
