The National Cancer Institute conducted a 2-year study to determine whether cancer death rates for areas nearnuclear power plants are higher than for areas without nuclear facilities. A spokesperson for the CancerInstitute said, "From the data at hand, there was no convincing evidence of any increased risk of death from anyof the cancers surveyed due to living near nuclear facilities."לי B. If the National Cancer Institute researchers were incorrect in their conclusion that there is no increased cancerrisk associated with living near a nuclear power plant, are they making a Type I or a Type II error? Readcarefully and select one of the following:a) A Type II error, if the researchers were incorrect in their conclusion this would be rejecting the null hypothesiswhen the null hypothesis is true.b) A Type I error, if the researchers were incorrect in their conclusion this would be failing to reject the nullhypothesis when the null hypothesis is true.c) A Type II error, if the researchers were incorrect in their conclusion this would be failing to reject the nullhypothesis when the null hypothesis is false.d) A Type I error, if the researchers were incorrect in their conclusion this would be rejecting the null hypothesiswhen the null hypothesis is false.

Type I error: The type I error if the null hypothesis is rejected when it is actually true. Type II…

Members of the Town of Colonie Golfers’ Loop frequently raise concerns to Mr. Lange, as its leader, about how the league is run. The most frequent concern raised is that the teams competing each week are not statistically even. In other words, members raise concerns that one or more teams have a statistical advantage over other teams. To evaluate the validity of these claims, Mr. Lange has decided to use a mix of statistical hypothesis tests discussed in this course to evaluate the teams from Outing #14 in calendar-year 2016 (2016, #14). One is the Equal Vari- ances F Test, one is Welch’s T Test, and the other is the 2-Sample T Test for Equal Means. In this particular outing, seven teams were competing for the win. A random sample of eight prior scores from each team member was collected, and the summary statistics are shown below (correct to three decimal places). team sample size sample mean sample variance 1 24 76.500 14.522 2 32 79.656 18.233…

According to the Centers for Disease Control and Prevention, 10.1% of high school students currently use electronic cigarettes. A high school counselor is concerned the use of e-cigs at her school is higher. Complete parts (a) through (c) below. (a) Determine the null and alternative hypotheses. 0.101 Ho: H₁: р 0.101 (Type integers or decimals. Do not round.) (b) If the sample data indicate that the null hypothesis should not be rejected, state the conclusion of the high school counselor. = > A. There is sufficient evidence to conclude that the proportion of high school students exceeds 0.101 at this counselor's high school. B. There is not sufficient evidence to conclude that the proportion of high school students stayed 0.101 at this counselor's high school. C. There is not sufficient evidence to conclude that the proportion of high school students exceeds 0.101 at this counselor's high school. D.

(D) decide whether to reject or fail to reject the null hypothesis and (e) interpret the decision in the context of the original claim. (Reject, fail to reject) the null hypothesis. There (is, is not) enough evidence to (support,reject) the center’s claim.
According to the Centers of Disease Control, about 22% of American young people between the ages of 12 and 19 are obese.A student claims that the students in his local schools are in better shape than the national average, so their proportion of obese students is less than 22%. Which are the appropriate null and alternative hypotheses for this study? H0: p = 22%, HA: p < 22% H0: p ≠ 0, HA: p = 0 H0: p = 22%, HA: p > 22% H0: p = 22%, HA: p ≠ 22% Suppose that the result is to Fail to reject H0.Which is the proper conclusion? There is sufficient evidence to support the claim that the students at his local schools have a smaller proportion of obese students. There is not enough information to answer this question. There is not sufficient evidence to support the claim that the students at his local schools have a smaller proportion of obese students.

Students in a Psychology Stats class gathered 1st and 2nd year university students to gather self-report data on UFO, sightings during the past year. A year later the same students took the survey after taking LSD. The results of the self-report survey are as follows: Participant ID UFO sightings UFO sightings before LSD after LSD 1 1 2 1 3 2 2 4 1 3 3 1 7 3 A) State the Null and Alternative Hypothesis. B) Find the calculated "t" value and the critical "t" value C) State weather to accept or reject the Null Hypothesis
When is a researcher at risk of making a type 2 error? whenever H0 is rejected whenever H1 is rejected whenever H0 fails to reject the risk of a type 2 is independent of the decision from a hypothesis test
