4. An herbal extract claimed to raise blood hemoglobin (Hb) level in anemic patientsmore than a placebo was tested as follows.Test 1. Two different samples (1 and 2, 10 subjects each) were obtained from the population,Sample 1 was given placebo and sample 2 was given the extract and the means of the sampleswere statistically compared based on X1 bar minus X2 bar.Test 2. 10 anemic subjects were gives capsules containing lactose for 1 month and their meanglucose level (BGL). The extract was given to the same subjects and Hb was measured againfor them. Differences between readings were obtained as placebo-herbal.If the question of interest was does the exact result in significant increase of Hb. The null andalternative hypothesis are stated asHO μ ≥ 0, vs HA μ< 0 for Test 1. HO: µ1-2 ≥ 0, vs HA: p1-u2 <0 for Test 2HO: μ1-μ2 ≥ 0, vs HA: 1- 2 <0 for Test 1. HO: μd 2 0, vs HA: μd <0 for Test 2HO μ = 0, vs HA: µd #0 for Test 1. Ho: p1- p2 = 0, vs HA: p1- µ2 #0 for Test 2HO: μ1-u2 s 0, vs HA: p1-u2 > 0 for Test 1. HO: ud s 0, vs HA: ud > 0 for Test 2HO: μd ≤ 0, vs HA: µd> 0 for Test 1. HO: μ1- 2 ≤ 0, vs HA: p1-u2 > 0 for Test 2

A special education teacher did research on whether or not there is a relationship between the number of students in his class and the number incidents of “acting out” behaviors exhibited by the autistic students in the classroom. He collects data for a year and aggregates them by month. He obtained the statistics below, r= -.863 R2=.74 b= -1.212294 a= 131.176598 10.) How does the presence of more students affect the incidents in the class? a) as students are added the incidences increase b) as students are added the incidences decrease c) the number of students does not affect acting out d) the number of students caused more incidents How much of the variability of acting out is explained by the number of students in the class?___________
Women are recommended to consume 1720 calories per day. You suspect that the average calorie intake is different for women at your college. The data for the 12 women who participated in the study is shown below: 1837, 1618, 1820, 1846, 1640, 1700, 1655, 1473, 1563, 1840, 1796, 1854 Assuming that the distribution is normal, what can be concluded at the αα = 0.10 level of significance? For this study, we should use Select an answer z-test for a population proportion t-test for a population mean The null and alternative hypotheses would be: H0:H0: ? μ p Select an answer > < ≠ = H1:H1: ? p μ Select an answer ≠ = < > The test statistic ? t z = (please show your answer to 3 decimal places.)

Suppose u1 and uz are true mean stopping distances at 50 mph for cars of a certain type equipped with two different types of braking systems. The data follows: m = 6, x = 115.6, s1 = 5.03, n = 6, y = 129.9, and s2 = 5.38. Calculate a 95% CI for the difference between true average stopping distances for cars equipped with system 1 and cars equipped with system 2. (Round your answers to two decimal places.) In USE SALT Does the interval suggest that precise information about the value of this difference is available? Because the interval is so narrow, it appears that precise information is available. Because the interval is so narrow, it appears that precise information is not available. o Because the interval is so wide, it appears that precise information is not available. o Because the interval is so wide, it appears that precise information is available.

QUESTION 2 To test the effect of a new medication on pulse rate, the researcher randomly selected the 60 subjects into two groups of 30. New medicine and placebo were given to Group 1 and Group 2, respectively. Below is the Minitab output. Two-Sample T-Test and CI Group Мean StDev SE Mean 1 30 65.20 7.80 1.4 2 30 70.30 8.40 1.5 Difference = mu (1) - mu (2) Estimate for difference: 95% CI for difference: T-Test of difference = 0 (vs not =): T-Value = -2.44 -5.10 (-9.29, -0.91) P-Value=0.018 DF=57 ii) Using to.025,57 = 2.003 shows that the 95% confidence interval for the difference in mean pulse rate between new medication and placebo is (-9.29, -0.91). Hence, interpret its meaning.
