# A consumer group claims that t

A consumer group claims that the mean minimum time it takes for a sedan to travel a quarter mile is greater than 14.8seconds. A random sample of 22 sedans has a mean minimum time to travel a quarter mile of 15.3 seconds and a standard deviation of 2.12 seconds. At α=0.05 is there enough evidence to support the consumer​ group’s claim? Complete parts​ (a) through​ (d) below. Assume the population is normally distributed.

​(a) Identify the claim and state H0 and Ha.

(b) use technology to find the P value. Find the standardized test statistic, t.

t=______

Obtain the P value

P=_______

(c)Decide whether to reject or fail to reject the null hypothesis:

(d) Interpret the decision in the context of the original claim:

# A consumer group claims that t

A consumer group claims that the average annual consumption of high fructose corn syrup by a person in the U.S. is 48.8 pounds. You believe it is higher. You take a simple random sample of 31 people in the U.S. and find an average of 53.9 pounds with a standard deviation of 4.2 pounds. Test at 5% significance.
