Solution Steps

Step 1: Find the percentage of the population 65 and older in 1950

According to the graph, the percentage of the population aged 65 and older in 1950 was 8%.

Step 2: Find the percentage of the population 65 and older in 2000

According to the graph, the percentage of the population aged 65 and older in 2000 was 12.4%.

Step 3: Calculate the relative change

Relative change is calculated using the formula: [(New Value - Old Value) / Old Value] * 100

In this case, the new value is 12.4% (the percentage in 2000) and the old value is 8% (the percentage in 1950). Therefore, the relative change is:

[(12.4 - 8) / 8] * 100 = (4.4 / 8) * 100 = 0.55 * 100 = 55

Final Answer: 55

Cadmium, a heavy metal, is toxic to animals. Mushrooms, however, are able to absorb and accumulate cadmium at high concentrations. Some governments have a safety limit for cadmium in dry vegetables at 0.48 part per million (ppm). A research team measured the cadmium levels in a random sample of edible mushrooms, where the hypothesis test is to decide whether the mean cadmium level in the sample is less than the governments' safety limit. The null and alternative hypotheses are H0: μ=0.48 ppm, Ha: μ<0.48 ppm. Complete parts (a) through (e) below. A. type II error B. correct decision because a false null hypothesis is rejected C. correct decision because a true null hypothesis is not rejected D. type I error e. Now suppose that the results of carrying out the hypothesis test lead to nonrejection of the null hypothesis. Classify that conclusion by error type or as a correct decision if in fact the mean cadmium level in that type of mushrooms is below the safety limit of 0.48 ppm . Choose the correct answer below. A. correct decision because a false null hypothesis is rejected B. type II error C. correct decision because a true null hypothesis is not rejected D. type I error
