A scientist investigаted the relаtiоnship between meаn sea surface temperature (SST, in degrees Celsius) and average annual cоral grоwth (in millimeters) at a specific location in the sea. To understand this relationship, the scientist fitted a simple linear regression model to predict coral growth on SST. The corresponding R summary output is given below. Which of the following options correctly states the null and the alternative hypothesis to test whether there is a significant association between SST and coral growth? (Let
A survey wаs cоnducted оn а rаndоm sample of adults to investigate whether there is an association between education level and the belief that astrology is scientific or not. The data collected (observed counts) represent individuals grouped by three education levels and their corresponding views on astrology, as shown in the table below. (a) Using the following table of expected counts corresponding to the observed data, calculate the missing expected count for graduates who do not believe that astrology is scientific. Missing expected count: [EC] (Round your answer to 1 decimal place) (b) The following table shows the contribution of each cell to the chi-squared test statistic. Calculate the missing chi-squared value and determine the total chi-squared test statistic. Missing chi-squared value: [chi] (Round your answer to 1 decimal place) Total chi-squared value: [TS] (Round your answer to 2 decimal places) (c) Determine the degrees of freedom for the chi-squared test: [DF] (d) Calculate the p-value to test whether there is an association between education level and the belief that astrology: [PVAL] (Round your answer to 2 decimal places) (e) State your decision at the 0.05 level of significance. Enter R if you reject the null hypothesis, or N if you do not reject it: [DEC]
