A random sample of 49 cans of soda is obtained and the contents are measured. The sample mean is 12.03 oz and the standard deviation is 0.13 oz. Test the claim that the contents of all such cans have a mean different from 12.00 oz, as indicated by the label. Use a 0.05 significance level. State the null and alternative hypotheses. A. H0: ? ? 12.00 oz Ha: ? = 12.00 oz B. H0: ? = 12.00 oz Ha: ? ? 12.00 oz C. H0: ? = 12.00 oz Ha: ? < 12.00 oz D. H0: ? = 12.00 oz Ha: ? > 12.00 oz Find the z-score. z = 1.62 (Round to two decimal places as needed.) Find the P-value. The P-value is [ ]. (Round to four decimal places as needed.)

Step 1
The null hypothesis is that the mean is equal to 12.00 oz, and the alternative hypothesis is that the mean is not equal to 12.00 oz. $$H_0: \mu = 12.00 \, \text{oz}$$ $$H_a: \mu \neq 12.00 \, \text{oz}$$ Show moreā¦

A random sample of 49 cans of soda is obtained and the contents are measured. The sample mean is 12.04 oz and the standard deviation is 0.11 oz. Test the claim that the contents of all such cans have a mean different from 12.00 oz, as indicated by the label. Use a 0.05 significance level. State what is the Null and alternative hypotheses? What is the Z score? (round to two decimal places). Find the P value? (round to four decimal places). State the conclusion choose the correct answer:A.The P-value is greater than the significance level. There is sufficient evidence to support the claim that the contents of all such cans have a mean different from 12.00 oz.B.The P-value is less than or equal to the significance level. There is not sufficient evidence to support the claim that the contents of all such cans have a mean different from 12.00 oz.C.The P-value is less than or equal to the significance level. There is sufficient evidence to support the claim that the contents of all such cans have a mean different from 12.00 oz.D.The P-value is greater than the significance level. There is not sufficient evidence to support the claim that the contents of all such cans have a mean different from 12.00 oz.

Soft-drink bottler claims that, on average, cans contain 12 oz of soda. Let X denote the actual volume of soda randomly selected from a can. Suppose that it is normally distributed with a mean of 12 oz and a standard deviation of 0.16 oz. Sixteen cans are to be selected and the soda volume determined for each one. Because the distribution is normal, the sampling distribution is also normal. With the bottler's claim correct, what is the probability that the sample contains an average of at least 12.1 oz?

Assume that cans of cola are filled such that the actual amounts have a population mean of Ī¼ = 12.00 ounces. A random sample of 49 cans has a mean amount of 12.37 ounces. The distribution of sample means of size n = 49 is normal with an assumed mean of 12.00 ounces, and those sample means have a standard deviation of 0.04 ounce. Complete parts (a) through (c) below. a. How many standard deviations is the sample mean away from the mean of the distribution of sample means? (Round to two decimal places as needed.)
