Vertical banded gastroplasty is a surgical procedure that reduces the volume of the stomach in order to produce weight loss. In a recent clinical study, 82 patients with Type 2 diabetes underwent this procedure, and 65 of them experienced a recovery from diabetes. Does this study provide evidence that more than 70% of those with diabetes who undergo this surgery will recover from diabetes? Use 0.05 as the level of significance. (a) State the null (H0) and alternate (Ha) hypotheses. H0: Ha: (b) If the null hypothesis is true, the sample proportion, p hat, has approxmately a Normal distribution with a mean of (blank) and a standard error of (blank). *(I need help on this one filling in the blank portions)*

A medical student at a community college in city Q wants to study the factors affecting the systolic blood pressure of a person (Y) Generally, the systolic blood pressure depends on the BMI of a person (B) and the age of the person A. She wants to test whether or not the BMI has a significant effect on the systolic blood pressure, keeping the age of the person constant. For her study, she collects a random sample of 125 patients from the city and estimates the following regression function: Y= 15.50 + 0..90B+1.15A. (0.55) (0 40) The test statistic of the study the student wants to conduct (Ho: B, = 0 vs. H, B, #0), keeping other variables constant is. (Round your answer to two decimal places.) At the 5% significance level, the student will ▼ the null hypothesis. Keeping BMIl constant, she now wants to test whether the age of a person (A) has no significant effect or a positive effect on the person's systolic blood pressure. So, the test statistic associated with the one-sided test the…
Brink studied the effect of postural change on cardiovascular reactivity for a sample of healthy white and African American men and women. Change in systolic blood pressure (SBP) from supine to standing position was used as the measure of cardiac reactivity in a sample of 842 adults. Supine measurement of blood pressure was taken after participants had lain on an examination table for 15 minutes. Blood pressure was measured five times every 2 minutes using a preset automated blood pressure monitor, and the five measurements were averaged. Participants then stood up, and an additional five measurements were made over another 10-minute period and then averaged. Below is a table describing the characteristics of Brink’s sample. Characteristics of the Study Sample (N = 842) Sample Characteristic Frequency (N) Percentage or Mean (SD) Range Gender Female Male 408 434 48.5% 51.5% Age (years) 842 55.1 (5.3) 44–67 Race/ethnicity White, not Hispanic…
Vertical banded gastroplasty is a surgical procedure that reduces the volume of the stomach in order to produce weight loss. In a recent study, 82 patients with type 2 diabetes underwent this procedure, and 59 of them experienced a recovery from diabetes. Does this study provide convincing evidence that the percentage of those with diabetes who undergo this surgery will recover from diabetes differs from 62%? Use the a = 0.10 level of significance and the p value method with the ti 84 plus calculator. State the appropriate null and alternate hypothesis. Computer the p value.

A certain drug can be used to reduce the acid produced by the body and heal damage to the esophagus due to acid reflux. The manufacturer of the drug claims that more than 92% of patients taking the drug are healed within 8 weeks. In clinical trials, 210 of 226 patients suffering from acid reflux disease were healed after 8 weeks. Test the manufacturers claim at the a=0.05 level of significance
As part of a study to determine the effects of a certain oral contraceptive on weight gain, 12 healthy females were weighed at the beginning of a course of oral contraceptive usage. They were reweighed after 3 months. Do the results suggest evidence of weight gain? Use α = .05.
A new cream that advertises that it can reduce wrinkles and improve skin was subject to a recent study. A sample of 68 women over the age of 50 used the new cream for 6 months. Of those 68 women, 39 of them reported skin improvement(as judged by a dermatologist). Is this evidence that the cream will improve the skin of more than 40% of women over the age of 50? Test using a= 0.05 (a) Test statistic: z= (b) The final conclusion is...A. There is not sufficient evidence to reject the null hypothesis that p=0.4 . That is, there is not sufficient evidence to reject that the cream can improve the skin of more than 40% of women over 50.B. We can reject the null hypothesis that p=0.4 and accept that p>0.4. That is, the cream can improve the skin of more than 40% of women over 50.
In a study, researchers wanted to measure the effect of alcohol on the hippocampal region, the portion of the brain responsible for long-term memory storage, in adolescents. The researchers randomly selected 13 adolescents with alcohol use disorders to determine whether the hippocampal volumes in the alcoholic adolescents were less than the normal volume of 9.02 cm cubedcm3. An analysis of the sample data revealed that the hippocampal volume is approximately normal with x overbarxequals=8.11 cm cubedcm3 and sequals=0.7 cm cubedcm3. Conduct the appropriate test at the alphaαequals=0.01 0.01 level of significance. State the null and alternative hypotheses. Upper H0: muμ ▼ less than< equals= not equals≠ greater than> nothing Upper H1: muμ ▼ not equals≠ equals= less than< greater than> nothing
Traumatic Brain Injury (TBI) is a significant health problem. TBI is caused by impacts to the head that might occurduring contact sports, motor vehicle accidents, and similar events. TBI is known to produce cognitive impairments and reductions in brain volume. In a recent, repeated-measures study on TBI, Zagorchev et al.(2016) observed that the size of the amygdala among mild TBI patients was reduced at 12 months after injury, relative to two months after injury. Suppose that a researcher is interested in replicating and extending this observation. She recruits n=8 participants with mild TBI and records the volume of a brain region at 2 months and again and again at 12 months. Her data are listed below a.) Test the hypothesis that volume of the brain region changed between 2 & 12 months. Use α=0.05, two-tailed b.) Compute the 80% confidence interval for the mean change in attention span for the population
A Pew poll taken in 2010 surveyed 830 people aged 18-29 and found that 166 of them had one or more tattoos. Based on this survey, can you conclude that the percentage of people aged 18-29 who have a tattoo is less than 25%? Use theα= 0.01 level of significance.
