A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 406406 gram setting. Based on a 1313 bag sample where the mean is 412412 grams and the standard deviation is 2121, is there sufficient evidence at the 0.0250.025 level that the bags are overfilled? Assume the population distribution is approximately normal.
Step 1 of 5 :
State the null and alternative hypotheses.
solve all steps please!!

Is there sufficient evidence at the 0.02 level that the bags are overfilled? Assume the population is normally distributed. State the null and alternative hypotheses for the above scenario.
A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 415 gram setting. Is there sufficient evidence at the 0.05 level that the bags are overfilled? Based on a 25 bag sample, the manufacturer decides to reject the null hypothesis. What is the conclusion?
A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 430 gram setting. It is believed that the machine is overfilling the bags. A 37 bag sample had a mean of 439 grams. Assume a population standard deviation of 29. Is there sufficient evidence at the 0.05 level that the bags are overfilled? 24. Step 1. State the hypotheses: Ho: Step 2. Find the value of the z test statistic. (Round your...
A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 447 gram setting. It is believed that the machine is overfilling the bags. A 31 bag sample had a mean of 455 grams. Assume the population variance is known to be 900. Is there sufficient evidence at the 0.1 level that the bags are overfilled? Step 2 of 6: Find the value of the test statistic. Round your answer to two decimal...
