Question in attachment
Using traditional methods it takes 11.8hours to receive a basic flying license. A new license training method using Computer Aided Instruction (CAI) has been proposed. Set up the hypotheses to test the claim at the 0.1level that the new technique performs differently than the traditional method. State the null and alternative hypotheses for the above scenario.

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.

Vegetarians are much less common in the United States than in the rest of the world. Suppose in a 2018 survey of 12,000 people in the United States, VeganBits found 60 who are vegetarians. (a) Develop a point estimate of the proportion of people in the United States who are vegetarians. (b) Set up a hypothesis test so that the rejection of H, will allow you to conclude that the proportion of people in the United States who are vegetarians exceeds 0.004. (Enter != for # as needed.) Ho: Ha: (c) Conduct your hypothesis test using a = 0.05. Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value.
