19 of 30 Ne II I have a dataset that lists the level of two blood proteins for each individual in a group of 100 people. My hypothesis is that the level of the first of these proteins depends on the level of the second protein. Assuming the levels of both proteins are Normally distributed, which of the following tests should I use to assess my hypothesis? 1-way ANOVA Paired, 2-tailed t-test O Spearman correlation Pearson correlation Unpaired, 2-tailed t-test

The null and alternative hypotheses for correlation are:`H0: ` == 0`Ha:` ≠≠ 0 The p-value is: (Round to four decimal places) Use a level of significance of α=0.05α=0.05 to state the conclusion of the hypothesis test in the context of the study. There is statistically significant evidence to conclude that a game with higher attendance will have fewer runs scored than a game with lower attendance. There is statistically significant evidence to conclude that there is a correlation between the attendance of baseball games and the runs scored. Thus, the regression line is useful. There is statistically insignificant…
