Use the steps in Hypothesis testing using the z-test. 33-45. A survey found that women over the age of 55 consume an average of 1660 calories per day. In order to identify if this applies in a certain city, the researcher sampled 43 women over the age of 55 and found that the mean number of calories they consume was 1446. The standard deviation was also found to be 56 calories. At 10% level of significance, can it be concluded that there is no significant difference between the number of calories consumed by women over age 55? Use two-tailed test.
