A large nationwide poll recently showed an unemployment rate of 9% in the US. Themayor of a local town wondersthis national result holds true for her town, so she planson taking a sample of her residents to see if the unemployment rate is significantlydifferent than 9% in her town. Let T represent the unemployment rate in her town. Hereare the hypotheses she'll use:Null Hypothesis: T = 0.09%3DAlternative Hypothesis: T 0.09Which type of Error has been committed in the following situation?• She concludes the town's unemployment rate is not significantly different to 9% whenit is actually 9%.Type II ErrorType I ErrorNo Error

Type I error: If the null hypothesis is rejected when it is actually true. Type II error: In case of…

Consider this study and identify the null hypothesis. (Remember: the null hypothesis is what Noel Hypothesis believes- that whatever interesting features you might think your data has are just coincidences.) An Uber driver's average customer rating is a 4.3. She decides to change how she greets passengers to a new greeting and see whether it changes how customers rate her. After the change, on her first 50 customers she sees an average rating of 4.47. Use u for her average rating from all customers using her new greeting. Ο Ημ 4.3 Hou > 4.3 Hoiu #4.3 Hou = 4.47 O Hou < 4.47 HoH+4.47
Last year 46% of business owners gave a holiday gift to their employees. A survey of business owners conducted this year indicated that 35% plan to provide a holiday gift to their employees. Suppose the survey results are based on a sample of 60 business owners. For hypothesis: H0: p >= .46 ; Ha:p < .46 , compute the P-value that could be used to determine whether the proportion of business owners providing holiday gifts has decreased from last year.
Kenya is a behavioral psychologist who works with children on the Autism Spectrum. She suggests that blowing bubbles may effect children's eye contact (she hasn't predicted if it would increase or decrease). She works with a student who makes 5 points of eye contact in a session. How would the NULL hypothesis be state for her study using bubbles? µ < 5 µ = 5 µ > 5 µ ≠ 5

You are conducting a study to see if the proportion of voters who prefer the Democratic candidate is significantly larger than 62% at a level of significance of a = 0.01. According to your sample, 62 out of 93 potential voters prefer the Democratic candidate. a. For this study, we should use z-test for a population proportion OF b. The null and alternative hypotheses would be: Ho: (p enter a decimal) OF H₁: p enter a decimal) 0° OF c. The test statistic (zŵ) = your answer to 3 decimal places.) d. The p-value = to 4 decimal places.) e. The p-value is a (please (Please (please show f. Based on this, we should (fail to reject î hypothesis. (Please show your answer the null
Fertilizer: A new type of fertilizer is being tested on a plot of land in an orange grove, to see whether it increases the amount of fruit produced. The mean number of pounds of fruit on this plot of land with the old fertilizer was 391 pounds. Agriculture scientists believe that the new fertilizer may increase the yield. State the appropriate null and alternate hypotheses. The null hypothesis is Ho:μ (choose one) and Answers The alternate hypothesis is H1:μ (choose one) and Answers

A sheriff's department claims that it pays its male and female employees equal wages. You analyze the wages they actually paid the deputies, and you find that the average hourly wage for males was $13.50 and for females it was $12.30. You conduct a t-test for this difference and get a t(obtained) of 1.31. (Hint: you will be using the two-sample hypothesis test) a. State the appropriate null and research hypotheses. b. If you had an alpha of .05 (one-tailed) with 60 degrees of freedom, what would be your t(critical)? c. Pretend you have a t(critical) of +2.000. Pretend you also calculated a t(obtained) of +1.31, write out a full interpretation based on the problem description above.
A well-known brokerage firm executive claimed that at least 24 % of investors are currently confident of meeting their investment goals. An XYZ Investor Optimism Survey, conducted over a two week period, found that out of 150 randomly selected people, 42 of them said they are confident of meeting their goals. Suppose you are have the following null and alternative hypotheses for a test you are running: Ho:p = 0.24 Ha:p + 0.24 Calculate the test statistic, rounded to 3 decimal places
The Statistics Games are played by a large number of students across the county. Last year, 32% of Clayton State students participated in the Games. You wonder: “Has the proportion increased this year?”. To find out, you take a random sample of 250 CSU students and ask them if they participated in the Games this year. You find that 38% did. Write the null and alternate hypotheses. A Ho: μ = 0.32 Ha: μ < 0.32 B Ho: μ = 0.32 Ha: μ ≠ 0.32 C Ho: p = 0.32 Ha: p > 0.32 D Ho: p = 0.32 Ha: p < 0.32 E Ho: p = 0.38 Ha: p > 0.38
A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal was 68%. Suppose that we have reason to believe that this proportion has changed, and we wish to carry out a hypothesis test to see if our belief can be supported. State the null hypothesis H, and the alternative hypothesis H that we would use for this test. H: 0 O
A December 2017 Gallup Poll reported that 43% of Americans use the internet for an hour or more each day. You suspect that a greater proportion of students at your school use the internet that much. You take a random sample of 60 students and find that 36 of them use the internet for an hour or more each day. Assume your school has more than 600 students. You will test the hypotheses H, : p = 0.43, H,:p>0.43 , where p= the true proportion of students at your school who use the internet for an hour or more each day. Which of the following gives the correct test statistic for this test? 0.43 - 0.6 Z = (0.6)(0.4) 60 0.43-0.6 (0.6)(0.4) 600 0.6-0.43 (0.6)(0.4) 60 0.6 - 0.43 (0.43)(0.57) 60 36 - 60 (36)(24) 60
