Answer: n = 14
Step-by-step explanation: margin of error = critical value × σ/√n
Where σ = population standard deviation = 1
n = sample size = ?
We are to construct a 99% confidence interval, hence the level of significance is 1%.
The critical value for 2 tailed test at 1% level of significance is gotten from a standard normal distribution table which is 2.58
Margin of error = 0.7
0.7 = 2.58×1/√n
0.7 = 2.58/√n
By cross multipying
0.7×√n = 2.58
By squaring both sides
0.7^2 × n = 2.58^2
0.49 × n = 6.6564
n = 6.6564/0.49
n = 14
The sequence is not geometric because there is no common difference or common ratio between each term. it’s also not an Arithmetic Sequence
Answer:
40 times
Step-by-step explanation:
8 times per 2 months
10 months / 2 months = 5 months
5 months x 8 times = 40 times
35% of 80 is 28.
80 x 0.35 = 28
I hope this helps.
