QUESTION 1 Various temperature measurements are recorded at different times for a particular city. The mean of 20'C is obtained for 60 temperatures on 60 different days. Assuming that the population standard deviation is 1.5 degrees C, test the claim that the population mean is 22 degrees C. Use a 0.05 significance level. Step 1: The alternative hypothesis is u (the symbol unless its not equal ) ( the number). The claim is (null or alternative). Step 2: The test value (z or t) = With a p-value of (4 decimals unless its 0). Step 3: Based on the p-value, you will (reject or FTR) the null hypothesis. Because the p-value is to the alpha. (use the symbol for this) Step 4: There enough evidence to the claim...The Z or T values use all of the numbers that excel gives you. The pvalues are always 4 decimals. Step 1: The alternative hypothesis is u [-----] (the symbol unless its not equal, then type in not equal) [------] ( the number). The claim is [------] (null or alternative). Step 2: The test value [-----] (z or t) =[----] (4 decimals) . With a p-value of [------] (4 decimals unless its 0). Step 3: Based on the p-value, you will [----] (reject or FTR) the null hypothesis. Because the p-value is [------] to the alpha. (use the symbol for this) Step 4: There [------] (is or is not) enough evidence to [-----] (support or reject) the claim
