Question

Four different types of fertilizers are used on raspberry plants. The number of raspberries on each randomly

selected plant is given below. Test the claim that the type of fertilizer makes no difference in the mean number

of raspberries per plant. Use α = 0.01.

Question

1)Perform the indicated one-way ANOVA test. Be sure to do the following: identify the claim and state the null and

alternative hypotheses. Determine the critical value and rejection region. Calculate the test statistic F. Decide to reject

or to fail to reject the null hypothesis and interpret the decision in the context of the original claim. Assume that each

population is normally distributed and that the population variances are equal.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
