The nicotine content in a single cigarette of a particular brand has a distribution with mean 0.4 mg and standard deviation 0.1
a_sh-v [17]

Answer:

Step-by-step explanation:

For this case we can define the random variable of interest as: "The nicotine content in a single cigarette " and for this case we know the following parameters:

\mu = 0.4, \sigma = 0.1

And for this case we select a sample size of n =100 and we want to find the following probability:

P(\bar X

And for this case we can use the z score formula given by:

z =\frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}

And replacing we got:

z= \frac{0.38-0.4}{\frac{0.1}{\sqrt{100}}}= -2

And we can find the required probability with the normal standard table and we got:

P(z

Jason ordered the numbers −70, −18, and −18.5 from least to greatest by writing the following statement:
ser-zykov [4K]

Answer:

No

Step-by-step explanation:

For negative numbers, the larger the number is the smaller its value is. For example -18 is greater than -18.5. This is because -18 is closer to 0 than -18.5 is. If you were to plot -18 and -18.5 on a number line you would see that -18 is closer to 0.
