Does soil without nitrogen decrease the weight of worms when compared to soil with nitrogen? The weights of 14 randomly selected
worms are taken, 7 in soil with nitrogen, and 7 in soil without nitrogen. The mean weights of worms in soil without nitrogen was 35.3 micrograms, while the mean weights of worms in soil with nitrogen was 36.3 micrograms. A researcher randomized the data over 100 trials, and the difference of means for each trial is shown in the dot plot below. What can the researcher conclude from this study?
a. The difference in weights is not significant because an original difference of means of –1 is very likely
b. The difference in weights is significant because an original difference of means of –1 is not very likely
c. The difference in weights is significant because an original difference of means of –1 is very likely
d. The difference in weights is not significant because an original difference of means of –1 is not very likely

The interest earned in 5 years would be $270
<u>Explanation:</u>
Given:
Principal, P = $1800
Rate of interest, r = 3%
Time, t = 5 years
Simple interest, I = ?
We know,
On substituting the value we get
Therefore, interest earned in 5 years would be $270
