(5 points) Weight gain during pregnancy. In 2004, the state of North Carolina released to the public a large data set containing information on births recorded in this state. This data set has been of interest to medical researchers who are studying the relationship between habits and practices of expectant mothers and the birth of their children. The following histograms show the distributions of weight gain during pregnancy by 840 younger moms (less than 35 years old) and 128 mature...

(6 points) Cars on Campus. Statistics students at a community college wonder whether the cars belonging to students are, on average, older than the cars belonging to faculty. They select a random sample of 23 cars in the student parking lot and find the average age to be 8.5 year with a standard deviation of 5.3 year. A random sample of 23 cars in the faculty parking lot have an average age of 3.4 years with a standard deviation of...

The mean weight gain during pregnancy is 30 pounds with a standard deviation of 12.9 pounds. If an obstetrician obtains a random sample of 35 patients, what is the probability that the mean weight gain during pregnancy from that sample is at least 34.5 pounds? That is, with n = 35, what is P(x≥34.5)?

In 2004, the FDA released a report suggesting that a particular class of antidepressants (selective serotonin reuptake inhibitors or SSRIS) may increase the risk of "suicidality" in adolescents. The concern led to a black box warning on SSRIS and other antidepressants for users younger than 25. The issue spurred a debate in the psychiatric research community concerning the core issue of whether suicidality, a measure of suicidal tendencies, accurately represents how likely an adolescent is to commit suicide. The reason...

(5 points) Consider each of the statements below. For each
statement, decide whether it is sometimes, always, or never a true
statement.
1. A hypothesis test that produces a positive
test statistic can produce a positive effect size. (Always,
Sometimes Or Never)
2. In order to compute Cohen's ?d, a
statistician must directly know the sample size. (Always,
Sometimes Or Never)
3. If two identical studies on the same topic
both produced estimated effect...

4. Nutrition scientists can calculate the amount of weight gain that would be associated with a given increase in calories. In one study, 16 non-obese adults, aged 25 to 36 years, were fed 1000 calories per day in excess of the calories needed to maintain a stable body weight. The subjects maintained this diet for 8 weeks, thus consuming a total of 56,000 calories extra. According to theory, 3500 extra calories will translate to weight gain of 1 pound. Therefore,...

(5 points) Consider each of the statements below. For each statement, decide whether it is sometimes, always, or never a true statement. 1. In general, increasing the sample size in a statistical study will decrease the standard error of the statistic computed from the sample. ? 2. If two identical studies on the same topic both produced estimated effect sizes less than d = 0.6, a third study that uses the same procedures will also produce an estimated effect size...

Hello if someone could help me with this multi part probably for the statistics? Thank you! Question 32q: A researcher is comparing two different weight-loss drugs. She splits her study participants into two halves randomly; every day for a month, one half (Group 1) takes Drug 1, and the other half (Group 2) takes Drug 2. She measures the total weight loss, in pounds, of each participant. A) Total Weight Loss of Each Participant at the end of the study...
