What is a random sample ?The process of selecting a sample of data from a population in order to draw conclusions about the population is known as random sampling. Additionally known as probability sampling. Non-probability sampling, often known as non-random sampling, is this sample's opposite. Simple random sampling, stratified sampling, cluster sampling, and multistage sampling are the main forms of this sampling. Convenience samples are often referred to as non-arbitrary samples in sampling methodologies.
Given that,
Population mean = $100
Sample = n = 56
Sample mean = $102.30
sample standard deviation = $5.30
So, all the data mean, standard deviation is given
therefore, t-test used and one type of sample used as well
Hence, It is one-sample t-test for sample mean

Mode and mean
Step-by-step explanation:
The measure of central tendency that can be determined by just looking at the box plot is : MEDIAN but the other measures of central tendencies. that cannot be determined accurately by just looking at the box plot . are MODE and MEAN
This simply because of how a box plot is created ( it makes it easier to determine the median value other than other central tendencies )

A population of 805 cheetahs decreases by 10% per year. How many cheetahs will there be in the population after 6 years?
Answer:
Step-by-step explanation:
y = a(b)^x
a would represent the initial value.
b would represent the change
x represents the number of years
y = 805(0.9)^6
y = 805(0.531441)
y = 427.8
y = 427 cheetahs

Question 10
A pair of sneakers is originally priced at
$125. They are on sale for $75. What is
the percent discount?
-please show your work
Answer: 40% discount
Step-by-step explanation:
First lets find the difference between original price and sale price so $125-$75= $50
So we get a discount of 50 dollars off the original price
Next lets find out how much of %$125 is that $50 so [tex]\frac{50}{125}[/tex] as a decimal is .4 or 40%. To check our work lets multiply 125 by 0.4 so 125*0.4= 50 which is the discount.

Put these numbers in descending order.
0.98
0.925
0.88
0.7
The descending values of the numbers is 0.98 > 0.925 > 0.88 > 0.7
Given data ,
Let the numbers be represented as A
Now , the value of A is
A = { 0.98 , 0.925 , 0.88 , 0.7 }
And , arranging in the descending order means from the greatest to the least value
So , the value of A is 0.98 > 0.925 > 0.88 > 0.7
Hence , the descending order is 0.98 > 0.925 > 0.88 > 0.7

every week a company provides fruit for its office employees. They can choose from among five kinds of fruit. What is the probability distribution for the 30 pieces of fruit, in the order listed?
(answer choices in the picture) PLZ HELP!
Answer:
option A 1/5, 3/10, 1/15, 4/15, 1/6
The probability distribution for the 30 pieces of fruit is,
A. 1/5, 3/10, 1/15, 4/15, 1/6.
What is a probability distribution?A probability distribution is a mathematical function used in probability theory and statistics that estimate the likelihood that various possible outcomes of an experiment will occur.
Given, Every week a company provides fruit for its office employees and the total number of fruits is 30 and the number of different types of food is
listed in the table.
Therefore, The probability distribution of apple (A) is 6/30 = 1/5.
Similarly, P(B) = 9/30 = 3/10.
P(L) = 2/30 = 1/15.
P(O) = 8/30 = 4/15.
P(P) = 5/30 = 1/6.
So, The distribution table is 1/5, 3/10, 1/15, 4/15, 1/6.
