Test of statistic (z-test or t-test) = Kind of test (one-tailed or two- tailed) = Level of Significance (0.01 or 0.05) = Accept the null hypothesis if the _________ is _________ than ________. Reject null hypothesis if the ________ is _____________than. Since the computed value is __________ than the critical value, we _________ the null hypothesis and ________ the alternative hypothesis. Therefore __________
Prices of basic commodities are often greatly affected by typhoons. During the aftermath of recent typhoon, the prices of tilapia were reported to have been sold at ₱20 – ₱25 more per kilogram at local wet markets. However, the price was back to its normal mean price at ₱100 per kilo one week after. If a random sample of 10 tilapia sales transactions from local wet markets have prices (in pesos per kilo) of 107, 115, 130, 95, 100, 105, 98, 116, 104, 100. Assuming that the tilapia prices are normally distributed, is there sufficient evidence to say that the mean price of tilapia in these markets is greater than ₱100? Use a 0.05 level of significance.
