Do teachers find their work rewarding and satisfying? An article reports the results of a survey of 390 elementary school teachers and 269 high school teachers. Of the elementary school teachers, 228 said they were very satisfied with their jobs, whereas 123 of the high school teachers were very satisfied with their work. Estimate thedifference between the proportion of all elementary school teachers who are satisfied and all high school teachers who are satisfied by calculating a 95% CI.

Do teachers find their work rewarding and satisfying? An article reports the results of a survey of 392 elementary school teachers and 268 high school teachers. Of the elementary school teachers, 226 said they were very satisfied with their jobs, whereas 122 of the high school teachers were very satisfied with their work. Estimate the difference between the proportion of all elementary school teachers who are satisfied and all high school teachers who are satisfied by calculating a 95% CI.

Mr. Tabor believes that less than 75% of the students at his school completed their math homework last night. The math teachers inspect the homework assignments from a random sample of 50 students at the school. Only 68% of the students completed their math homework. We want to test ?0:?=0.75;??:?<0.75H0:p=0.75;Ha:p<0.75, where ?p = the true proportion of the students at Mr. Tabor’s school who completed their math homework last night. A significance test yields a ?P-value of 0.1265. What it would mean for the null hypothesis to be true in this setting? 1. Mr. Tabor’s students complete 75% of their homework last night. 2.cIf ?0:?=0.75H0:p=0.75 is true, then the proportion of the homework that the students at Mr. Tabor’s school completed last night is 0.75. 3. If ?0:?=0.75H0:p=0.75 is true, then the proportion of the sample who completed their homework last night is 0.75. 4. If ?0:?=0.75H0:p=0.75 is true, then the proportion of all students at Mr.…
Do teachers find their work rewarding and satisfying? An article reports the results of a survey of 399 elementary school teachers and 261 high school teachers.

The proportion of Americans who have frequent migraines is 15.2% according to the CDC. An acupuncturist claims that her treatment can reduce this figure significantly. A random sample of 260 Americans is administered the acupuncturists treatment and 31 report experiencing migraines.a. State Hypotheses to the scenario using the correct symbols. b. What is the sample proportion? (Round to 2 decimal places) ˆpp^=c. Suppose the P-value is calculated to be 0.0427What would your decision be for this test using α=α= 0.05? fail to reject the null reject the null accept the null Write a conclusion in terms of the acupuncturist's claim.

The math teachers inspect the homework assignments from a random sample of 50 students at the school. Only 68% of the students completed their math homework. We want to test Ho p = 0.75 H. p + 0.75 where p = the true proportion of the students at Mr. Tabor's school who completed their math homework last night. A significance test yields a P-value of 0.1265. What conclusion would you make at the a = 0.05 level? O Because the P-value is greater than = 0.05, we fail to reject Ho. O Because the P-value is higher than the difference between the population parameter and the sample statistic, we fail to reject Ho. Because the P-value is too less than a = 0.05, we fail to reject Ho. O Because the P-value is less than a = 0.05, we reject Ho. O Because the P-value is greater than x =…

It’s assumed that students need to stay awake more to study during finals week. One way to measure this is how much coffee is consumed during Finals week at night. A local coffee house near APU counted the number of cups of coffee sold per hour during Finals week after 6 p.m. We randomly select ten (10) hours of sales records during Finals week and find out that the following number of cups of coffee were consumed: 18, 17, 22, 14, 17, 20, 22, 24, 15, 15 By comparison, the sales records from a previous week were used as a comparison. The following number of cups of coffee were consumed over a seven (7) hour period: 9, 13, 5, 15, 17, 10, 11 a. Determine what is the appropriate statistical procedure, with a brief explanation (one sentence) as to why this is the appropriate procedure. b. State the null hypothesis. c. Execute the proper calculations with the appropriate procedures. d. Present a graph when appropriate of your results. e. Include any appropriate post-hoc tests. f. State…
