A good faith estimate is required by law to be given by the lender to the borrower within three days of submitting a loan applic

tensa zangetsu [6.8K]

Answer: The loan estimate is standardized, and lists services you are allowed to shop for. You may not be able to shop for an appraisal fee or a credit report fee, but be able to shop for a land survey and title insurance. Lenders will vary in their requirements. Explanation: The Good Faith Estimate (GFE) was designed to encourage consumers to shop and then compare fees from various lenders before choosing a mortgage provider. Its original purpose was to help consumers understand what services they could shop for-so they not only received the lowest interest rate and best terms but saved significantly on closing costs as well.

A professor would like to test the hypothesis that the average number of minutes that a student needs to complete a statistics e

professor190 [17]

Answer:

$\chi^2 =\frac{15-1}{25} 16 =8.96$

The degrees of freedom are given by:

$df = n-1 = 15-1=14$

The p value for this case would be given by:

$p_v =P(\chi^2$

Since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true deviation is not ignificantly lower than 5 minutes

Step-by-step explanation:

Information given

$n=15$ represent the sample size

$\alpha=0.05$ represent the confidence level

$s^2 =16$ represent the sample variance

$\sigma^2_0 =25$ represent the value that we want to verify

System of hypothesis

We want to test if the true deviation for this case is lesss than 5minutes, so the system of hypothesis would be:

Null Hypothesis: $\sigma^2 \geq 25$

Alternative hypothesis: $\sigma^2$

The statistic is given by:

$\chi^2 =\frac{n-1}{\sigma^2_0} s^2$

And replacing we got:

$\chi^2 =\frac{15-1}{25} 16 =8.96$

The degrees of freedom are given by:

$df = n-1 = 15-1=14$

The p value for this case would be given by:

$p_v =P(\chi^2$

Since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true deviation is not ignificantly lower than 5 minutes

Calculate 11010-1101 in base 2

stiv31 [10]

Answer:

1101 base 2

Step-by-step explanation:

you first take the larger number up the the lower number down

11010 -1101
when dividing if it's zero you borrow one from the number on the left hand side
since it's in base 2 the number you borrow would be 2 then u subtract
I hoped it helped u
