Suzette went to the mall with her uncle Louie and ended up having to borrow some money to finish her holiday shopping. Suzette s

aw an egg-beater that she wanted to get for her sister. It cost $12.00 and she said to her uncle, “If you will lend me as much money as I currently have in my wallet, I will buy the beautiful beater for Betty.” He agreed and lent her the money. At another store she found a handsome slide rule for her brother, also for $12.00. She made the same deal with her uncle. “If you will lend me as much money as I currently have in my wallet, I will buy the rad rule for Robert.” Once again, he agreed. Finally, Suzette decided to splurge on a CD for herself, which also happened to cost $12.00. You guessed it. She made the same deal with her uncle. This time however, after completing the transaction, her wallet ended up empty. How much money did Suzette have at the beginning of her shopping spree?

2. Graph x < 8 and x > -1.
dimulka [17.4K]

Answer:

I'll try my best in explaining the steps.

Considering both signs are greater than and less than sign, its an open circle.

For the first equation, you would have an open circle, basically one that isn't colored in, on 8 on the number line. The arrow would be pointing to the left because the equation is telling us numbers that are less than 8.

For the second equation, you would have an open circle, basically one that isn't colored in, on -1 on the number line. The arrow would be pointing to the right because the equation is telling us numbers that are greater than -1.

A researcher collated data on Americans’ leisure time activities. She found the mean number of hours spent watching television e
ikadub [295]

The value of the z statistic for the considered data is given by: Option A: -3.87 approximately.

<h3>How to find the z score (z statistic) for the sample mean?</h3>

If we're given that:

  • Sample mean = \overline{x}
  • Sample size = n
  • Population mean = \mu
  • Sample standard deviation = s

Then, we get:

z = \dfrac{\overline{x} - \mu}{s}

If the sample standard deviation is not  given, then we can estimate it(in some cases) by:

s = \dfrac{\sigma}{\sqrt{n}}

where \sigmapopulation standard deviation

For this case, we're specified that:

  • Sample mean = \overline{x} = 2.3
  • Sample size = n = 15
  • Population mean = \mu  = 2.7
  • Population standard deviation = \sigma = 0.4

Thus, the value of the z-statistic is evaluated as:

z = \dfrac{\overline{x} - \mu}{\sigma/\sqrt{n}} = \dfrac{2.3- 2.7}{0.4/\sqrt{15}} \approx -3.87

Thus, the value of the z statistic for the considered data is given by: Option A: -3.87 approximately.
