Hi, can you please help me with the questions in the image by following the below instructions.

a. identify the claim and state H₀andH_a.

b. find the standardized test statistic z or t OR find the corresponding P-value.

c. Identify the type of test. Compare the p-value with ? OR the standardized test statistic with the critical value of z or t

d. decide whether to reject or fail to reject the null hypothesis. based on the test statistic or the p-value

e. interpret the decision in the context of the original claim.

4. A consumer group claims that the mean acceleration time from 0 to 60 miles per hour for a sedan is 6.3 seconds. A random sample of 33 sedans has a mean acceleration time from 0 to 60 miles per hour of 7.2 seconds. Assume the population standard deviation is 2.5 seconds. At a = 0.05, can you reject the claim? (Source: Zero to 60 Times) 5. Caffeine Content: A consumer research organization states that the mean caffeine content per 12-ounce bottle of a population of caffeinated soft drinks is 37.7 milligrams. You want to test this claim. During your tests, you find that a random sample of thirty-six 12-ounce bottles of caffeinated soft drinks has a mean caffeine content of 36.4 milligrams. Assume the population standard deviation is 1 0.8 milligrams. At a = 0.01, can you reject the research organization's claim? (Source: National Soft Drink Association) 6. Fast Food: A fast-food restaurant estimates that the mean sodium content in one of its breakfast sandwiches is no more than 920 milligrams. A random sample of 44 breakfast sandwiches has a mean sodium content of 925 milligrams. Assume the population standard deviation is 18 milligrams. At a = 0.10, do you have enough evidence to reject the restaurant's claim? 7. Light Bulbs: A light bulb manufacturer guarantees that the mean life of a certain type of light bulb is at least 750 hours. A random sample of 25 light bulbs has a mean life of 745 hours. Assume the population is normally distributed and the population standard deviation is 60 hours. At a = 0.02, do you have enough evidence to reject the manufacturer's claim
