Step-by-step explanation:

a) The range at which the internal temperature can rise is from 2°F to 6°F, which means that in order fo the final temperature of the turkey to fall within the range of 165-170°F, we need to pull remove the turkey when the internal temperature is at a minimum of 164°F or a maximum of 168°F.

b) I'd rather err on the higher side of the internal temperature. After all, no one eats poultry cooked medium rare due to the high probability of salmonella poisoning and the 165-170°F is meant to destroy the microbes that causes food poisoning. Not only that, poultry meat gets sufficiently cooked at that range.

Answer:

One: Median = 2

Two: Mean = 3.25

Step-by-step explanation:

One

Put the dots in order

1 1 1 2 2 3 3

There are seven groups altogether.

The middle one is a 2.

The median is 2.

Two

The mean is the average.

The average of the 4 groups is

1 3 6 3 = 13

The average is the sum of the dots.

13/4 = 3.25

Answer:

$z=\frac{750-800}{\frac{350}{\sqrt{100}}}=-1.429$

Step-by-step explanation:

Data given and notation

$\bar X=750$ represent the sample mean

$\sigma=350$ represent the population standard deviation for the sample

$n=100$ sample size

$\mu_o =800$ represent the value that we want to test

$\alpha$ represent the significance level for the hypothesis test.

t would represent the statistic (variable of interest)

$p_v$ represent the p value for the test (variable of interest)

State the null and alternative hypotheses.

We need to conduct a hypothesis in order to check if the mean is lower than 800, the system of hypothesis would be:

Null hypothesis: $\mu \geq 800$

Alternative hypothesis: $\mu < 800$

If we analyze the size for the sample is > 30 and we know the population deviation so is better apply a z test to compare the actual mean to the reference value, and the statistic is given by:

$z=\frac{\bar X-\mu_o}{\frac{\sigma}{\sqrt{n}}}$ (1)

z-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".

Calculate the statistic

We can replace in formula (1) the info given like this:

$z=\frac{750-800}{\frac{350}{\sqrt{100}}}=-1.429$
