You are given data on number of radio ads and sales for a local department store. You had observations for 20 months. The correlation between ads and sales is 0.40. Does this indicate a positive and significant relationship between ads and sales at the 5% level of significance
Answers
Answer:
"No" would be the appropriate response. A further explanation is provided below.
Step-by-step explanation:
According to the question,
Number of observations,
n = 20
Significance level,
d = 5%
i.e.,
= 0.05
Calculated correlation,
= 0.40
Critical correlation value will be:
= 0.444
According to the question, we can see that the calculated correlation i.e., "0.40" is far less than the critical correlation value i.e., "0.444". The null hypothesis has always been not rejected. Thus it doesn't indicate the significant relationship.So the above it the right response.

Find the value of ln(-0.379).
Answers
Answer:
Undefined
Step-by-step explanation:
To obtain the In(-0.375)
In x = log e x = y
The In is the natural logarithm of a number
To obtain the natural logarithm value of a given number using a calculator :
Simply press the In button followed by the value to obtain the direct value of the number x.
The In of any negative value gives an error output.
The In of x is only defined for values of x greater Than 0; that is ; X > 0
In of negative numbers is undefined

A six-week fitness program was designed to decrease the time it takes retired individuals to walk one mile. At the beginning of the program, 20 randomly selected retired individuals were invited to participate, and their times to walk a mile were recorded. After the six-week program, their times to walk a mile were again recorded. Most participants saw little to no improvement in their times to walk one mile; however, a few participants saw drastic improvements in their times to walk one mile. The program director would like to perform a hypothesis test to determine if the program reduces the mean time for retired individuals to walk a mile. Which of the following statements is true?
a. Because there are 40 observations in total, the sample size is large enough to assume that the sampling distribution of the sample mean differences is approximately normal.
b. Because the walk times before and after the program are paired, a hypothesis test is not appropriate.
c. The sampling distribution of sample means can be assumed to be approximately normal because the distribution of the sample data is not skewed.
d. Because the sample size of 20 is less than 30 and the improvements in walk times in the sample data appear to be skewed, the distribution of sample means should not be assumed to be approximately normal.
e. Because the program recruited only retired individuals, the distribution of sample means should not be assumed to be approximately normal.
Answers
Answer:
c. The sampling distribution of the sample means can be assumed to be approximately normal because the distribution of the sample data is not skewed
Step-by-step explanation:
From the given data, we have;
The category of the sample = Retired individuals
The number of participants in the sample = 20
The duration of program = six-weeks
The improvement seen by most participants = Little to no improvement
The improvement seen by few participants = Drastic improvement
Therefore, given that the participants are randomly selected and the majority of the participants make the same observation of improvement in the time to walk a mile, we have that, the majority of the outcomes show little difference in walk times after the program, therefore, the distribution of the sample data is not skewed and can be assumed to be approximately normal

Step-by-step explanation:
FGE is a straight line, and striaght lines measure 180 by definition. Therefore, x, angle BGA, and 55 all add together to equal 180. But notice that x and 55 are both marked with a single swish, meaning they are the same measure. So:
180 - 55 - 55 = x, so
x = 70
Jessica's school bus stop is 60 yards from her house. For a normal school week, how many feet will Jessica walk to and from the bus stop.
Answers
Answer:
1,800 feet
Step-by-step explanation:
Assuming that the normal school week is 5 days, she will walk for 5 days to and from. Each day she will walk 120 yards to and from the stop. Multiply that number by 5 and you get your answer of 600 yards. The answer is wanted in feet, so you have to consider yards to feet conversions. 1 yard is three feet. Therefore, you multiply 600 by 3 and you get your answer in feet.

The parameter for the exponential distribution,
