Answer:
a
The 95% confidence interval is
b
The result obtained does not contradict expectation
Step-by-step explanation:
From the question we are told that
The number of green peas is k = 438
The number of yellow peas is u = 173
Generally the sample size is mathematically represented as

=>
=> 
Generally the sample proportion for yellow peas is

=> 
=> 
From the question we are told the confidence level is 95% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of
is
Generally the margin of error is mathematically represented as
=>
=>
Generally 95% confidence interval is mathematically represented as
=>
=>
From the question we are told that it was expected that 25% of the offspring peas will be yellow
Now from the 95% confidence interval obtained we see that the expected sample proportion(25% ) falls within it so it means that the result obtained does not contradict expectation
Answer:
x = 5.6
Step-by-step explanation:
Look at the given congruent angles and what sides are opposing to write the proportions. After writing the proportions solve for the unknown x.
Answer:
About 150,000
Step-by-step explanation:
Round because you are finding <u>about </u>how many people attended (I’m just doing it in my way; are multiple ways to round and multiple answers):
52,104 ≈ 52,100
48,899 ≈ 48,900
49,023 ≈ 49,000
Add:
52,100 + 48,900 + 49,000 = about 150,000 people attended
