An SAT prep course claims to improve the test score of students. The table below shows the scores for seven students the first two times they took the verbal SAT. Before taking the SAT for the second time, each student took a course to try to improve his or her verbal SAT scores. Do these results support the claim that the SAT prep course improves the students' verbal SAT scores? Let d = (verbal SAT scores prior to taking the prep course)-(verbal SAT scores after taking the prep course). Use a significance level of α = 0.05 for the test. Assume that the verbal SAT scores are normally distributed for the population of students both before and after taking the SAT prep course.

If you hypothesize that there is no difference between means, this means the alternative hypothesis is ??: ?1 = ?2 Determine whether the statement is true or false. If the statement is false, EXPLAIN why.
A baseball team claims that the mean length of its games is 2.4 hours. State H0 and Ha in words and in symbols. Then determine whether the hypothesis test for this claim is left-tailed, right-tailed, or two-tailed. Explain your reasoning. State the null hypothesis in words and in symbols. Choose the correct answer below. A. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at most 2.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≤2.4." B. The null hypothesis expressed in words is, "the mean length of a baseball team's games is more than 2.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≠2.4." C. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at least 2.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≥2.4." D. The null hypothesis expressed in words is, "the mean length of a baseball…
This is a homework question: Since the question is claiming the order is super fast but NOT faster than...would this be a non-directional? Brittany sees an ad for a new mobile restaurant delivery service that claims to bring your food order super fast. She wants to compare the time it takes the delivery with the new app (WheelDeliver) to the time it takes the delivery with UberEats. What is the null hypothesis for this scenario? Wheel delivery is equal to UberEats

Suppose Aaron recently purchased an electric car. The person who sold him his new car told him that he could consistently travel 200 mi before having to recharge the car's battery. Aaron began to believe that the car traveled even farther than the company claimed, and he decided to test this hypothesis formally. Aaron drove his car only to work and he recorded the number of miles that his new car traveled before he had to recharge its battery a total of 17 separate times. The table shows the summary of his results. Assume his investigation satisfies all conditions for a one-sample t-test. Mean miles traveled Sample size t-statistic P-value P 207 17 1.48 0.079 The results statistically significant at a = 0.01 because P 0.01. are are not V
The proportion of the population in favor of a particular law was about 66%. It is believed that the current proportion of the population in favor of the law has decreased. To assess this, you collect a sample of n=340 people and 197 indicate being in favor of the law. We wish to test the claim that the proportion of the population in favor of the law has decreased. Symbolically, the claim would be expressed as the alternative hypothesis: Ha:p
A certain hypothesis is tested by three similar experiments. These gave x² = 11-9 for v = 6, x² = 14-2 for v = 8 and x² = 18-3 for v= 11. 2 H Show that the three experiments together provide more justification for rejecting the hypothesis than any one experiment alone.
