Step-by-step explanation:

<em>Since it starts at 0 and goes to -2.5, that means that he owes $2.50</em>

<em>Since it goes from -2.5 to 6.25, that means that he ears $8.75</em>

For each situation, state the null and alternative hypotheses: (Type "mu" for the symbol μ , e.g. mu > 1 for the mean is grea

Nitella [24]

Answer:

Part (A) $H_0:\mu=2.5$ and $H_a:\mu\neq2.5$

Part (B) $H_0:\mu=16.35$ and $H_a:\mu$

Step-by-step explanation:

Consider the provided information.

Null hypothesis refers the population parameter is equal to the claimed value.

If there is no statistical significance in the test then it is know as the null which is denoted by $H_0$ , otherwise it is known as alternative hypothesis denoted by $H_a$ .

Part (A): The diameter of a spindle in a small motor is supposed to be 2.5 millimeters (mm) if the spindle is either too small or too large, the motor will not work properly.

Thus, the required null and alternative hypothesis are:

$H_0:\mu=2.5$ and $H_a:\mu\neq2.5$

Part (B) The nationwide average price of a certain brand of laundry detergent is $16.35 and Harry thinks that prices in Caldwell are lower than the rest of the country.

Thus, the required null and alternative hypothesis are:

$H_0:\mu=16.35$ and $H_a:\mu$

A 2-column table with 5 rows. the first column is labeled x with entries negative 4, negative 1, 0, 2, 3. the second column is l

Licemer1 [7]

The linear function that models the data in the table is $y = \frac{3}{2}x + 1$

<h3>How to determine the linear model?</h3>

The table of values is given as:

x y

-4 -6

-1 -1

0 1

2 4

3 7

The linear equation is calculated using:

$y = \frac{y_2 -y_1}{x_2 - x_1} * (x - x_1) + y_1$

So, we have:

$y = \frac{4 -1}{2 - 0} * (x - 0) + 1$

Evaluate the differences

$y = \frac{3}{2}x + 1$

Hence, the linear function that models the data in the table is $y = \frac{3}{2}x + 1$
