Answer:
$33333.33
Step-by-step explanation:
Suppose x invested into the bank account that pays 4% simple Interest
5x4%x+5x6.4%(50000)= 12000 { The interest due is equal to interest}
4x+6.4x50000-6.4x=240000
2.4x=80000
x=33333.33

Answer:
95% confidence interval for nasturtiums in a 50 gram bag is (1.442, 1.700)
Step-by-step explanation:
The sample is:
1.45g, 1.35g, 1.45g, 1.65g, 1.72g, 1.45g, 1.35g, 1.92g, 1.76g, and 1.61g.
Sample size is 10
Mean nasturtiums in a 50 gram bag is
Standard deviation of the sample is the mean of the squared differences from the mean(0.181)
95% Confidence Interval can be calculated using M±ME where
- M is the mean nasturtiums in a 50 gram bag (1.571 g)
- ME is the margin of error from the mean
And margin of error (ME) can be calculated using the formula
ME= where
- t is the corresponding statistic in the 95% confidence level and 9 degrees of freedom (2.262)
- s is the standard deviation of the sample (0.181)
- N is the sample size (10)
Then ME= =0.129
95% confidence interval for nasturtiums in a 50 gram bag is 1.571±0.129
