Construct hypotheses based on a given observation and determine if a given scenario is using deductive or inductive reasoning.  3. Jackie observed that most of the houses in her neighborhood did not set out recycling cans on trash pick-up day. She wondered if the lack of participation was due to apathy and decided to conduct a formal survey. Write a specific, testable research hypothesis and null hypothesis for Jackie’s observation. Justify your reasoning.

short answer Ethics:  Which hypothesis, the null or the alternative, is easiest for the math to support?  Knowing that, could someone state their hypothesis so that it is the most likely to be supported?  Should every hypothesis test be done with various wordings of the claim, or is there a structure to the hypotheses that should be followed?

2. Toastmasters International cites a report by Gallup Poll that 40% of Americans fear public speaking. A student believes that less than 40% of students at her school fear public speaking. She randomly surveys 361 schoolmates and finds that 137 report they fear public speaking. Conduct a hypothesis test at the 5% level to determine if the percent at her school is less than 40%. a. State the null hypothesis. b. State the alternative hypothesis. c. Construct a 95% confidence interval for the true proportion. Sketch the graph of the situation. Label the point estimate and the lower and upper bounds of the confidence interval. (Round your answers to four decimal places.)

Determine the type of error.

At a nearby college, there is a school-sponsored website that matches people looking for roommates. According to the school's reports, 43% of students will find a match their first time using the site. A writer for the school newspaper tests this claim by choosing a random sample of 170 students who visited the site looking for a roommate. Of the students surveyed, 58 said they found a match their first time using the site. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.10 level of significance, to reject the claim that the proportion, P, of all students who will find a match their first time using the site is 43%. (a) State the null hypothesis H, and the alternative hypothesis A that you would use for the test. P H 0 D=0 DO (b) For your hypothesis test, you will use a Z-test. Find the values of MP and n(1-p) to confirm that a Z-test can be used. (One standard is that Mp2 10 10 under the assumption that the null hypothesis is true.)…

A student majoring in Management who has passed the Business Statistics course suspects that the average price of lunch at the canteen has increased during the pandemic. Before the pandemic, the price for lunch he paid was $21, $22, $22.50, $23, $23.50. After the pandemic, he paid $25, $25.50, $30, $27, and $26.50. a) Perform a hypothesis test analysis to find out whether there has been an average increase in the price of lunch (Use six Hypothesis Testing Steps) ! b) Interpret (and explain) the results of point a above!

Dr. Moo conducted a research project in which she compared the impact of two types of therapy (pizza therapy and chocolate therapy) and gender on college students’ happiness. How many null hypotheses did she have, and how would you write them?

At a nearby college, there is a school-sponsored website that matches people looking for roommates. According to the school's reports, 39% of students will find a match their first time using the site. A writer for the school newspaper tests this claim by choosing a random sample of 160 students who visited the site looking for a roommate. Of the students surveyed, 54 said they found a match their first time using the site. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.10 level of significance, to reject the claim that the proportion, p, of all students who will find a match their first time using the site is 39%. (a) State the null hypothesis H, and the alternative hypothesis H₁ that you would use for the test. Ho: H₁:0 р 0<0 0<0 □□ 0=0 (b) For your hypothesis test, you will use a Z-test. Find the values of np and n (1-p) to confirm that a Z-test can be used. (One standard is that np≥ 10 and (1-p) ≥10 under the assumption that the…

At a nearby college, there is a school-sponsored website that matches people looking for roommates. According to the school's reports, 38% of students will find a match their first time using the site. A writer for the school newspaper tests this claim by choosing a random sample of 165 students who visited the site looking for a roommate. Of the students surveyed, 48 said they found a match their first time using the site. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.05 level of significance, to reject the claim that the proportion, p, of all students who will find a match their first time using the site is 38%. (a) State the null hypothesis H, and the alternative hypothesis H, that you would use for the test. OSO H: I D=D0 (b) For your hypothesis test, you will use a Z-test. Find the values of np and n (1-p) to confirm that a Z-test can be used. (One standard is that npz 10 and n (1-p) > 10 under the assumption that the null…
