Answer:
The 2000 CDC growth charts were developed using a reference population of infants. A pediatrician looks up one of the charts and finds that the 10th percentile for weights of baby boys at 3-1/2 months is 10.9 pounds. This means that *** about 10%*** of the 3-1/2-month-old baby boys in the reference population weigh 10.9 pounds or less, and ***about 90%*** of these baby boys weigh 10.9 pounds or more.
Step-by-step explanation:
Percentiles indicate the position or standing of a value as compared to the general set of values in the same sample space. They indicate the values below which a certain percentage of the data in a data set is found.
The nth percentile of a set of data is the value at which n percent of the data is below it.
Like in this example, the 10th percentile is the value (or score) below which 10% of the observations may be found. Similarly, 90% of the observations are found above the 20th percentile.

Answer:
0.6 is the probability of success of a single trial of the experiment
Complete Problem Statement:
In a binomial experiment with 45 trials, the probability of more than 25 successes can be approximated by 
What is the probability of success of a single trial of this experiment?
Options:
Step-by-step explanation:
So to solve this, we need to use the binomial distribution. When using an approximation of a binomially distributed variable through normal distribution , we get:
=
now,
so,
by comparing with , we get:
μ=np=27
=3.29
put np=27
we get:
=3.29
take square on both sides:
10.8241=27-27p
27p=27-10.8241
p=0.6
Which is the probability of success of a single trial of the experiment
20.50 * 0.8 = $16.40
16.40 * 0.4 = $6.56
Final selling price = $6.56
