Answer:
C.
Step-by-step explanation:
Also known as left-skewed distribution, a negatively skewed distribution would have data that are more concentrated on the right side. So you would see a longer tail on the left-side of the distribution or curve. You would find the mean to the left of the median of the data.

If you have a graphing calculator, go to 2nd vars, normalcdf(.
Put 150 for the lower bound and 99999999 for the upper bound. You want to know the probability of all the values over 150. Put 131.8 for the mean and 29.12 for the standard deviation. Click paste.
Your answer will be .266
Answer:
2%
Step-by-step explanation:
Given data
Principal=$2300
Simple interest=$906.20
Time= 19.7years
Required
The rate in percentage
We know that
SI=PRT/100
substitute
906.20=2300*R*19.7/100
906.20=45310R/100
cross multiply
906.20*100= 45310R
90620= 45310R
R= 90620/45310
R=2%
Hence the rate is 2%
