researcher is investigating US resident’s natural disaster preparedness. The researcher wants to test if less than 40% of US residents have a “natural disaster emergency plan”. To test this, the researcher selected a sample of 1000 US residents. Each sample member was asked if they have a “natural disaster emergency plan”. Of the 1000 samples, 371 responded that they did have a “natural disaster emergency plan”. Conduct the appropriate Hypothesis Test using ∝=.05. The steps of the hypothesis test are provided below: Step 1: State the null and alternative hypotheses one would use to test if less than 40% of US residents have a “natural disaster emergency plan”. Step 2: What distribution/model should be use to conduct this hypothesis test?(If using statistical features on your calculator then what test will you use?) Step 3: State rejection rule. Step 4: Provide the p-value. (From you calculator output or explain how you determined it) Step 5: Using ∝=.05, draw a conclusion. Should the null hypothesis be rejected? Yes or No? Why? Step 6: Summarize your Step 5 results in the context of the question posed.

In a recent survey, it was stated that Americans watch television on average four hours per day. Assume that σ = 2. Using 40 students as the sample, conduct a hypothesis test to determine if the average for students at your school is lower:
According to the National Highway and Traffic Safety Administration, the proportion of fatal traffic accidents in the United States in which the driver had a positive blood alcohol concentration (BAC) is .36. Suppose a random sample of 105 traffic fatalities in the state of Hawaii results in 51 that involved a positive BAC. D) Check whether the conditions for hypothesis testing using the P-value approach are meet.
An opinion poll was conducted to examine people's satisfaction with the work of civil defense during the coronavirus epidemic. 200 people were asked and 180 of them said they were satisfied with the work of the civil defense. The polling company also conducted a hypothesis test with the hypotheses below and found that the value of the test size was 1.88. H0 : p = 0,85 H1 : p ≠ 0,85 What is the p-value of the hypothesis test?
According to a restaurant owner, the percentage of kindergartners in the U.S. who say pancakes are their favorite food is less than 25%. Out of 200 randomly selected kindergartners who were surveyed, 45 said that pancakes are their favorite breakfast food. Using a complete test of hypothesis with a = 0.05 , is there enough evidence to support the claim of the restaurant owner? You may refer back to the previous problem for the steps required for a test of hypothesis.
A health provider saw that 48% of their members received their flu shot in recent years. The health care provider tried a new advertising strategy the following year, and they took a sample of members to test if the proportion who received their flu shot had changed. Determine the null and alternative hypothesis
According to a recent census,16% of the people in the United States are of Hispanic origin. One county supervisor believes her county has a different proportion of Hispanic people than the nation as a whole. She looks at their most recent survey data, which was a random sample of 402 county residents, and found that 49 of those surveyed are of Hispanic origin. What are the appropriate conditions for a hypothesis test?
According to the 2010 Census, 16% of people in the United States are of Hispanic or Latino origin. One Vigo County supervisor believes her county has a lower proportion of Hispanic people than the nation as a whole and questions the validity of the Census. She looks at the county's most recent survey data, a random sample of 400 county residents, and found that 44 of those surveyed are of Hispanic or Latino origin. a. Identify an appropriate null and alternative hypothesis for a test to be conducted by the county supervisor. b. Would the hypothesis test be one or two tailed? Z or T test? Upper or lower? Explain your response.

2. The average U.S. household has $235,600 in life insurance. A local insurance agent would like to see how households in his city compared to the national average, and selects a simple random sample of 30 households from the city. For households in the sample, the average amount of life insurance is ? = $245,800 with s = $25,500. Using a non-directional hypothesis test and a level of significance of 90%, what conclusion would be reached?
Last year, 44% of business owners gave a holiday gift to their employees. A survey of business owners conducted this year indicates that 30% plan to provide a holiday gift to their employees. Suppose the survey results are based on a sample of 80 business owners. (a) How many business owners in the survey plan to provide a holiday gift to their employees this year? ( ) business owners (b) Suppose the business owners in the sample did as they plan. Compute the p-value for a hypothesis test that can be used to determine if the proportion of business owners providing holiday gifts has decreased from last year. Find the value of the test statistic. (Round your answer to two decimal places.) ( ) Find the p-value. (Round your answer to four decimal places.) p-value = (c) Using a 0.05 level of significance, would you conclude that the proportion of business owners providing gifts decreased? Reject H0. There is sufficient evidence to conclude that the…
