Can I please have an explanation for these problems? Thank you!

I) 3') Use each dropdown menu below to complete the null hypothesis and the alternative hypothesis statements for the following problem situation. According to a report from the Center for Disease Control and Prevention (CDC), in 2017, only 24.3% of American adults met the Physical Activity Guidelines set by the Department of Health and Human Services. Test the claim that the percentage was lower among Americans who live in colder climate regions for at least four months out of the year.

On average, an American generates 4.5 pounds of trash each day. Test the claim the mean is higher among Americans who have children. H0 3 [Select] v [Select] v 45 Ha : l: [Select] V 4.5 Use each dropdown menu below to complete the null hypothesis and the alternative hypothesis statements for the following problem situation. According to a study from Instantly in the year 2015, 12% of Americans do not eat breakfast. Test the claim the percentage is different this year. H0 : [Select] v [Select] V 0.12 Ha : [Select] V 0.12 'H-VAII '0 Use each dropdown menu below to complete the null hypothesis and the alternative hypothesis statements for the following problem situation. An insurance company claims that the mean amount of wait time for roadside assistance is no longer than 30 minutes. Test the claim that the mean is longer than 30 minutes. H0 2 [Select] v [Select] v 30 Ha 3 E [SEIECt] v 30 Home BBQ gas grills typically use rellable propane tanks as fuel. The capacity of one type of tank is 15 pounds. One particular vendor discloses that their tanks have a mean of 15 pounds and a standard deviation of 0.52 pound. Assume the distribution is approximately normal. In a random sample of 18 tanks, the mean is 14.8 pounds. Find the p-value to test the claim that the mean is less than 15 pounds. Express the answer as a decimal value rounded to the nearest thousandth. a\\ For patrons who prefer to ride on the stationary bike at a gym, the trainer recommends riding for an average (mean) of 45 minutes during each session. Assume the distribution of times is approximately normal. In a random sample of 23 stationary bike riders at the gym, the mean time is 51 minutes with a standard deviation of 13 minutes. Find the p-value to test the claim that the mean time is not 45 minutes. Express the answer as a decimal value rounded to the nearest thousandth. 7) 50 From the year 2004 through 2013, 23% of gunshot wounds in the United States were due to accidental discharge of weapons. Treat the 23% as the population proportion. In a random sample of 125 gunshot wounds taken this year, 37 were determined to be due to accidental discharge. Find the pvalue to test the claim that the proportion of accidental gunshot wounds is higher this year. Express the answer as a decimal value rounded to the nearest thousandth. Suppose the p-value is 0.22 for a hypothesis test at the 2.5% level of signicance. What is the correct decision? O Reject the null hypothesis and support the alternative hypothesis 0 Do not reject the null hypothesis
