Answer:

9,384 electronic keyboards.

Step-by-step explanation:

<u>Question asked:</u>

How many electronic keyboards, on average, are sold each year in Alaska?

<u>Solution:</u>

Let number of electronic keyboards, on average, are sold each year in Alaska = x

<u>Given:</u>

The number of electronic keyboards sold in New York is eight times the average number of electronic keyboards sold each year in Alaska:-

On an average, keyboards sold in New York = 8 times that of Alaska

75,072 = 8\times x\\ \\  75,072=8x\\ \\ Dividing\ both \ sides\ by\ 8\\ \\ \frac{75072}{8} =\frac{8x}{8} \\ \\ 9384=x

Therefore, 9,384 electronic keyboards, on average, are sold each year in Alaska.

Nutka1998 [239]

Answer: 1.303639

Step-by-step explanation:

The t-score for a level of confidence (1-\alpha) is given by :_

t_{(df,\alpha/2)}, where df is the degree of freedom and \alpha is the significance level.

Given : Level of significance : 1-\alpha:0.80

Then , significance level : \alpha: 1-0.80=0.20

Sample size : n=40

Then , the degree of freedom for t-distribution: df=n-1=40-1=39

Using the normal t-distribution table, we have

t_{(df,\alpha/2)}=t_{39,0.10}=1.303639

Thus, the t-score should be used to find the 80% confidence interval for the population mean =1.303639
