Answer:
<h2>168.75 g</h2>
Step-by-step explanation:
the required mass of flour = (3÷4)×225 = 168.75
Area of triangle = (1/2)*b*h = (1/2)*7*10
= 7*5 = 35 squared cm
Answer: The 95% confidence interval will be wider.
Step-by-step explanation:
Confidence interval for population proportion is written as
Sample proportion ± margin of error
margin of error = z score × √pq/n
The z score is determined by the confidence level. The z score for a confidence level of 95% is higher than the z score for a confidence level of 90%
This means that with all other things being equal, a 95% confidence level will give a higher margin of error compared to a 90% confidence level.
The higher the margin of error, the wider the confidence interval. Therefore,
The 95% confidence interval will be wider.
