Answer (1-3 with complete solutions) Situation Number 1A company has developed a new battery. The engineering department of the company claims thateachbattery lasts for 200 minutes. In order to test this claim, the company selects a random sample of 100new batteries so that this sample has a mean of 190 minutes. Given that the population standarddevi ation is 30 minutes, test the engineering department's claim that the new batteries run with anaverage of 200 minutes. Use 1% level of significance. 1. Which is the correct null hypothesis that can be derived in thesituation? *The average runtime of the batteries is equal to 200 minutes.The average runtime of the batteries is greater than 200 minutes.The average runtime of the batteries is less than 200 minutes.The average runtime of the batteries is not equal to 200 minutes.2. Which is the correct alternative hypothesis that can be derived in thesituation? *The average runtime of the batteries is less than 200 minutes.The average runtime of the batteries is greater than 200 minutes.The average runtime of the batteries is not equal to 200 minutes.The average runtime of the batteries is equal to 200 minutes.3. What test will be used based from the given values in the situation? *z-test since n2 30 and ois knownz-test sincen<30 and o is unknownt-test since n2 30 and o is known1-test since n>30 and ois unknown

The appropriate hypothesis is to be set up to validate the claim that, if the mean battery run time…

A company has developed a new battery. The engineering department of the company claims that each battery lasts for 200 minutes. In order to test this claim, the company selects a random sample of 100 new batteries so that this sample has a mean of 190 minutes. Given that the population standard devi ation is 30 minutes, test the engineering department's claim that the new batteries run with an average of 200 minutes. Use 1% level of significance.
