A soil scientist has just developed a new type of fertilizer and she wants to determine whether it helps carrots grow larger. She sets up several pots of soi and plants one carrot seed in each pot. Fertilizer is added to half the pots. All the pots are placed in a temperature-controlled greenhouse where they receive adequate light and equal amounts of water. After two months of growth, the scientist harvests the carrots and weighs them (in kilograms). Belo is a data table showing the weight of the carrots at the end of the growing period from the two treatment groups. Here is a hyperlink to the data. When analyzing this dataset with a t-test, the null treatment are the same, whereas the alternate hypothesis states that the average size of the carrots from each hypothesis states that the fertilized carrots are larger in size. -tailed t-test. To analyze this data set, the scientist should use a one After performing a t-test assuming equal variances using the data analysis add-in for MS Excel, what is the calculated t-value for this data set? -3.6211 Round your answer to 4 decimal places. Report your answer as the absolute value of your calculated t statistic. Report the appropriate critical t value, based on your decision of a one- or two-tailed test, calculated by MS Excel-using the Data Analysis add-in. Round your answer to 4 decimal places. What is the appropriate p value for the t-test? 3.09e-4 Report your answer in exponential notation Report your answer to 4 decimal places after converting to exponential notation eg. 1.1234E-01 for 0.112341 o 3.1234E-04 for 0.000312341 Would you reject or fail to reject the null hypothesis? reject
