I NEED HELP!!! WILL MARK BRAINLIEST!!! HHHEELLLPPP!!!!

The estimate of the total sales is $3,055,510.08.

First I created a scatter plot of the data given for yellow golf balls and calculated the linear regression for it.  Screenshots are attached.

The regression equation (equation for the line of best fit) was 
y = 16488x + 189312, where x represents the year number and y is the total yellow golf balls.

We are concerned with year 4, so we will substitute 4 for x:
y = 16488(4) + 189312 = 255,264

There will be around 255,264 yellow golf balls sold in year 4.

Since the ratio of yellow to white golf balls is 1:5, we can set up a proportion:
1/5 = 255264/x

Cross multiply:
1*x = 5*255264
x = 1,276,320

We expect the company to sell 1,276,320 white golf balls.  This makes a total of:

1,276,320 + 255,264 = 1,531,584 total golf balls expected to be sold in year 4.

Since these are sold in boxes of 12, we divide this by 12:
1,531,584/12 = 127,632 boxes expected to be sold

Each box is 23.94:
127632*23.94 = 3,055,510.08

What is The area of a parallelogram with a length of 7 cm and a with of 2 cm
yawa3891 [41]

Answer:

14cm^2

Step-by-step explanation:

\text {Formula for area of a parallelogram: } A=l*h\\\text {l is the length. h is the height.}

l = 7

h = 2

7 * 2 =14\\\boxed {\text {The area of the parallelogram should be 14cm squared.}}

A null hypothesis can only be rejected at the 5% significance level if and only if:
ozzi

Answer:

Option (B) a 95% confidence interval does not include the hypothesized value of the parameter              

Step-by-step explanation:

Alpha, α = 0.05

We conduct a hypothesis test at 5% significance level.

The null hypothesis will be rejected when

Option (B) a 95% confidence interval does not include the hypothesized value of the parameter

  • When a 95% confidence interval is constructed,it contains all the possible values for the parameter being estimated.
  • If the value of the parameter stated in the null hypothesis is contained in the 95% confidence interval, then we fail to reject the null hypothesis 0.05 level and accept it.
  • If the value stated in the null hypothesis is not in the interval, then we fail to accept the null hypothesis and reject the null hypothesis at the 0.05 level.
