(10/23/2020) On Friday, I asked a beautiful blond Dutch Girl out. I believe she's 24 Yr.

• She giggled

• She smiled at me in surprise.

Basically, she'll be busy for two weeks, but she'll let me know a date.

I knew she was kinda into me, so I made my move.

So do you think I got a chance?

How has cyber-bullying personally affected you?

On Excel:

Meal  |                 Frequency |  Relative Frequency 

_________________________________________

Breakfast |                      55.  |            0.55 

_________________________________________

Lunch |                            10  |            0.10 

_________________________________________

Dinner |                            23 |            0.23 

_________________________________________

None of the above |        12  |             0.12 

_________________________________________

Total   |                        100    |

Relative Frequency = Frequency/total

In Statistics and Modeling, ~ 100 people were asked what was the most important meal of the day.

• Breakfast 55 

• Lunch 10 

• Dinner 23 

• None of the above 12 

How do I create a frequency table and include the relative frequencies?

A GSS asked, "what do you think is the ideal number of children for family to have? For the 555 males in the sample, the mean was 2.89 and the standard deviation was 1.77.              

-What is the standard error of the sample mean?             

-What's the 95% confidence interval for the population mean?             

According to a union agreement, the mean income for all senior-level assembly-line workers in a large company equals $500 per week. A representative of a women's group decides to analyze whether the mean income, for female employees matches this norm. For a random sample of nine female employees, y=$1210 and s=190.                        

What is the mean income of female employees differs from $1500 per week?                   

- What were the null hypotheses?                         

- What were the alternative hypotheses?                           

- What was the test statistic?                              

- What was the P-Value?                                

- What Interpret the result, that is the conclusion?

A GSS asked, "what do you think is the ideal number of children's for family to have? For the 555 males in the sample, the mean was 2.89 and the standard deviation was 1.77           ��

How do I find the standard error of the sample mean?        

And how do I Find the 95% confidence interval for the population mean?        

A marketing class made a random selection of 150 shoppers at a shopping mall to participate in a taste test of different brands of coffee. The class found that 54 shoppers preferred Brand X. The proportion favoring Brand X is _____.

130 people were studied. The mean was 98.249 degrees with a standard deviation of 0.733 degrees. 

The group had significantly different average body temperature from the rest of the adult population. 

The average body temperature for an adult is 98.

What can a person solve from this?
