A cereal company claims that the mean weight of the cereal in its packets is over 14 oz. A random sample of 48 cereal packets has a mean of 14.3 oz and a standard deviation of 1.1 oz. Use a significance level of .05 to test the company's claim. Express the null hypothesis and the alternative hypothesis in symbolic form. H0: ? = 14 H1: ? > 14 H0: ? > 14 H1: ? ? 14 H0: ? < 14 H1: ? ? 14 H0: ? = 14 H1: ? < 14

Step 1
Define the null hypothesis (H0) and the alternative hypothesis (Ha). The null hypothesis (H0) is that the mean weight of the cereal packets is equal to 14 oz, and the alternative hypothesis (Ha) is that the mean weight is greater than 14 oz. H0: μ = 14 Ha: μ > Show more…

Assume that a simple random sample has been selected from a normally distributed population and test the given claim. You can use either the traditional method or P-value method. Identify the null and alternate hypotheses, test statistic, critical value(s) or P-value (or range of P-values) a appropriate, and state the final conclusion that addresses the original claim. A cereal company claims that the mean weight of the cereal in its packets is 14 oz. The weight (in ounces) of the cereal in a random sample of 8 of its cereal packets are listed below. 14.6 13.8 14.1 13.7 14.0 14.4 13.6 14.2

'For cereal company; the content weight for box of cereal is normally distributed With mean OZ. sample of 20 such boxes produces mean of 15.8 0z and standard deviation of 0.5 0z. Find 95% confidence interval for /4. For the hypotheses Ho pl = 16 HA p # 16. find the test statistic and p-value. What is the conclusion with level of signifi- cance 0.05? Show that null value /lo will be in the confidence interval if and only if Ho is not rejected (in a two-sided test).'

A herd of 1500 cattle was fed a special high-protein grain for a month. A random sample of 30 cattle was weighed and had gained an average of 7.3 pounds. If the standard deviation of weight gain for the entire herd is 5.3 pounds, test the hypothesis that the average weight gain per cow for the month was more than 7 pounds. Null Hypothesis: H₀: μ = 7 Alternative Hypothesis: Hₐ: μ > 7 (a) Calculate the P-value. (b) Based on α = 0.05, what is the correct conclusion for the hypothesis test?
