Extracted text: and the rejection region and (d) draw a conclusion. In each of the following problems (a) state the null and the alternative 3.4 kg. The average weight of a random sample of 30 newly born 26. It is claimed that that the average weight of babies at birth is compute the test statistic, (c) determine the critical value babies was determined. It was found out that the average weight MASH MATH hypotheses (b) at was 3.1 kg. Is there a reason to believe that the average weight of babies at birth is not 3.4 kg? Assume that the population standard deviation is 1.1 kg. Use 0.05 level of significance. It is claimed that the mean annual salary of customer service call center representatives is P188,584.00. A researcher randomly selected 45 customer service call center representatives. He computed the mean of their annual salaries and obtained a mean of P188,600.00. Does this show that the mean salary of customer service call center representatives is greater than P188,584.00? Use 0.05 level of significance and assume the population standard deviation is P39.50.
