The calculated t-value is t=0.47.
Step-by-step explanation:
<em>The question is incomplete:</em>
<em>"Americans typically eat quickly and do not spend time enjoying their meal. A researcher plans to test if those trained in mindfulness will take more time to enjoy their meal (that is, they will spend more time eating than the general population). The general population spends an average of 68 minutes per day combined eating their three meals. The researcher trains a sample of 16 individuals in mindfulness and then collects data on how long they spend eating per day. The sample mean for those trained in mindfulness equals 74; the SS = 150. What is the calculated t-value? Round your answer to two decimal places."</em>
The degrees of freedom are (n-1)=(16-1)=15
The standard deviation is:

The t-value can be calculated as:

Answer:
76.8
Step-by-step explanation:
Using the proportion
→ Percent is out of 100
=
( cross- multiply )
100n = 7680 ( divide both sides by 100 )
n = 76.8
10 (> or = to) 2.00 + 0.75x
Sorry. I don't have that symbol on my keyboard. but her ten dollars has to be greater than or equal to whatever the cost is so that's why that symbol has to be used in this case. 2.00 is the flat rate and add 0.75 multiplied by however many miles she is taking!
Hope this helps!
