Greetings!

"10-3" can also be written as:
1) -3+10
2)10+(-3)

Hope this helps.

Another way for writing that is "subtract 3 from 10"

A simple random sample of size nequals40 is drawn from a population. The sample mean is found to be 103.9, and the sample stand

yan [13]

Answer:

There is enough evidence to support the claim that the population mean is greater than 100

Step-by-step explanation:

Step 1: We state the hypothesis and identify the claim

$H_0:\mu=100$ and $H_1:\mu \:>\:100$ (claim)

Step 2: Calculate the test value.

$t=\frac{\bar X-\mu}{\frac{s}{\sqrt{n} } }$

$\implies t=\frac{103.9-100}{\frac{21.9}{\sqrt{40} } }=1.1263$

Step 3: Find the P-value. The p-value obtained from a calculator is using d.f=39 and test-value 1.126 is 0.134

Step 4: We fail to reject the null hypothesis since P-value is greater that the alpha level. (0.134>0.05).

Step 5: There is enough evidence to support the claim that the population mean is greater than 100.

Alternatively: We could also calculate the critical value to obtain +1.685 for $\alpha=0.05$ and d.f=39 and compare to the test-value:

The critical value (1.685>1.126) falls in the non-rejection region. See attachment.

NB: The t- distribution must be used because the population standard deviation is not known.

Norman buys two cakes. One cake cost 40 cents and the other costs a quarter. How much does he spend in total?

Ivan

Answer: 50 cents

Step-by-step explanation:

Norman buys two cakes. One cake cost 40 cents and the other costs a quarter. Based on this, the cost of the second cake will be:

= 1/4 × 40

= 10 cent

Now, the total amount spent in total will be:

= 40 cents + 10 cents

= 50 cents
