solve for this with 6 step of hypothesis testing TESTING HYPOTHESISInstructionsInstructionsAnswer the following with complete steps:1. Average Senior High School annual costof tuition fee for all private school lastyear was P46,300. A random sample ofcosts this year for 45 private schoolsindicated that the sample mean wasP47,800 and a sample standard deviationwas P5,600. At the 0.10 level of ofsignificance, is there sufficient evidenceto conclude that the cost has increased?Use 6-steps in hypothesis testing.

I need help with stats/2023, section 7.1, Determine whether the claim stated below represents the null hypothesis or the alternative hypothesis. If a hypothesis test is performed, how should you interpret a decision that (a) rejects the null hypothesis or (b) fails to reject the null hypothesis? A report claims that more than 74% of households in a specific county struggle to afford basic necessities. Does the claim represent the null hypothesis or the alternative hypothesis? Since the claim (1) ______________ (contains or does not contain) a statement of equality, it represents the (2) ________________ (null or alternative) hypothesis. (a) How should you interpret a decision that rejects the null hypothesis? There (3) ___________ (is or is not) enough evidence to (4)_____________ (reject or support) the claim that more than 74% of households in a county struggle to afford basic necessities.

Angel believes a coin is “fair,” the other believes the coin is biased toward heads. The coin is tossed 20 times, yielding 15 heads. Indicate whether or not the first researcher’s position is supported by the results. Use α = .05. Express statistically the null and alternative hypotheses.
A former residential complex was found to be a Superfund site polluted with several hazardous materials. Tamela is an investigative journalist who would like to show whether the proportion of the residents of the complex who eventually died from cancer is greater than the regional average of 14%. She randomly selects 54 residents who lived in the complex and finds that 12 of those residents eventually died from cancer. Are all of the conditions for this hypothesis test met, and if so, what are the null and alternative hypotheses for this hypothesis test? Select the correct answer below: Although the proportion follows a binomial model with two independent outcomes and the data are selected at random, the number of successes and the number of failures are not both greater than or equal to 5. Although the proportion follows a binomial model with two independent outcomes and the number of successes and the number of failures are both greater than or equal to 5, the…
Using the P-value method decide if you should reject the null hypothesis or not. In a sample of 81 adults selected from one town, it is found that 8 of them have been exposed to a particular strain of the flu. At 0.01 level of significance, you wish to test the claim that the proportion of all adults in the town that have been exposed to this strain of the flu is 8%.
A risky eye surgery for patients in danger of permanent blindness is known to historically cure the condition in 35% of all cases of performing the surgical procedure. A new procedure is proposed for which the researchers claim that they will improve that rate of cure. -Write an appropriate null and alternate hypothesis for the researchers to test their claim.
