The prices оf Hоndа CRV cаrs аre nоrmally distributed with a mean of $33,300 and a standard deviation of $3000. If one Honda CRV is randomly chosen, what is the probability that its price is less than $30,000.? Round your response to 4 decimal places. [q1] 88% of Honda CRV prices are between [lower] and [upper]. Round to the nearest dollar. Suppose a random sample of 40 Honda CRVs is chosen. Complete the sentence below to describe the sampling distribution of the mean for samples of size 40. Be sure to address the shape, the mean of the sampling distribution and the standard error of the mean. Where rounding is necessary, round to the nearest dollar. The sampling distribution of the mean is [shape] with a mean of [mean] and standard error of [se]. What is the probability that a random sample of 40 Honda CRV's results in a mean price of more than $34,000? The probability is [prob]. (Round to 4 decimal places) Complete the sentence to interprest the probability from part 4. If [100s] were chosen from this population, we'd expect about [number] to have a mean price of more than $34,000.
