Answer:
Step-by-step explanation:
a₆ = a₇+(6-7)d = -4 -(-5) =1
D) Function 2, because Jack spends $8 each week and Tom spends $7 each week
Answer: 1) $9000
2) $5340
3)59.3%
Step-by-step explanation:
Since we have given that
Worth of life insurance = $60000
Amount of premium = $900
After the end of 10 years,
1) Amount of premium Tom had paid is given by

2) At the end of 10 years ,
The cash value of his policy by using the table is given by

3) At the end of 10 years ,
Ratio of cash value to premiums paid be

The critical values corresponding to a 0.01 significance level used to test the null hypothesis of ρs = 0 is (a) -0.881 and 0.881
<h3>How to determine the critical values corresponding to a 0.01 significance level?</h3>
The scatter plot of the election is added as an attachment
From the scatter plot, we have the following highlights
- Number of paired observations, n = 8
- Significance level = 0.01
Start by calculating the degrees of freedom (df) using
df =n - 2
Substitute the known values in the above equation
df = 8 - 2
Evaluate the difference
df = 6
Using the critical value table;
At a degree of freedom of 6 and significance level of 0.01, the critical value is
z = 0.834
From the list of given options, 0.834 is between -0.881 and 0.881
Hence, the critical values corresponding to a 0.01 significance level used to test the null hypothesis of ρs = 0 is (a) -0.881 and 0.881
