Answer
44,005 + 5,001+ 100,009 + 93 + 3,000,007+ 7,000
Step-by-step explanation:
Answer:
a: The mean of 800 customers per day
b: See below
c: z = -1.43
d: 0.0764
e: Fail to reject the null
Step-by-step explanation:
b: The hypotheses are:
H0: µ = 800
HA: µ < 800 (claim)
The mean number of daily customers was 800. She feels the number of customers has decreased, so the alternate is mu is less than 800.
c: See attached photo for the calculation of the test statistic
d: The probability is on the z table. Find the decimal that corresponds to the z-value of -1.43, which is: 0.0764
e: Since 0.0764 > 0.05, we fail to reject the null hypothesis. There is not enough evidence to support the claim that the number of customers visiting the dealership has decreased.
To simplify the process of expanding a binomial of the type (a+b) n (a + b) n, use Pascal's triangle. The same numbered row in Pascal's triangle will match the power of n that the binomial is being raised to.
A triangular array of binomial coefficients known as Pascal's triangle can be found in algebra, combinatorics, and probability theory. Even though other mathematicians studied it centuries before him in India, Persia, China, Germany, and Italy, it is called after the French mathematician Blaise Pascal in a large portion of the Western world. Traditionally, the rows of Pascal's triangle are listed from row =0 at the top (the 0th row). Each row's entries are numbered starting at k=0 on the left and are often staggered in relation to the numbers in the next rows. The triangle could be created in the manner shown below: The top row of the table, row 0, contains one unique nonzero entry.
