A study was done to compare people's religion with how many days that they have said they have been calm in the past three days.
0 days 1 day 2 days 3 days Protestant 50 27 6 16 Catholic 55 19 2 11 Jewish 84 34 4 18 Other 84 34 2 22 What proportion of Protestants were calm for 2 out of the 3 days? NOTE: Read the question very carefully.
1 answer:
Answer:
The probability of the number of Protestants that were calm for 2 out of 3 days is 0.061.
Step-by-step explanation:
Represent the provided data as follows:
Compute the probability of the number of Protestants that were calm for 2 out of 3 days as follows:
The number of Protestants surveyed is, <em>n</em> (Protestants) = 99.
The number of Protestants who were calm for 2 days,
<em>n</em> (Protestants who were calm for 2 days) = 6
The required probability is:
Thus, the probability of the number of Protestants that were calm for 2 out of 3 days is 0.061.

Answer:
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:
