Marc saved $2,533 in January than in December.
Step by Step calculation.
Given the details below :
Salary In December =$3,650
In January, Increased by 12%
Marc saves 30% of $3,650 in December
New salary can then be calculated as :
= Initial salary * % increase / 100 + Initial salary
= 3,650 * 12 / 100 + 3,650
= 3,650 * 0.12 + 3,650
= 4,088
The difference will now be
= 4,088 - 3650
= $438
Since Marc saves in December 30% of $3,650
= 30% of $3,650
= $1,095
Saves in January
= 1,095 + 438
= $2,533

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
