Use the following data to answer questions 1-4For many years the value of concentration of fertilizers has been 2.3 but now it seems that no fertilizers are either below or above the 2.3 but never 2.3 data has been collected and the following values for concentrations have been found 2.1,2.5,2.8,3.0,2.2,2.4,2.9 (Answer questions 1-4 from the data above) Assume a normal distrubution Chapter 9 1.) From the data above what is the null hypotheses? 2.) From the data above what is the alternate hypotheses? 3.) Is it a left tailed, right tailed or two tailed test? 4.) Calculate z if theta is 0.3?
