The null hypothesis is that the average high temperature in December is 45 degrees. If someone reports that the average was 52 d

Vanyuwa [196]

P-value approach is used to take a decision to reject or accept the null hypothesis as indicated below:
REJECT the hypothesis, if p-value FAIL TO REJECT the hypothesis, if p-value > the alpha value.
Alpha value represents the level of significance 
If alpha value is NOT indicated: alpha = 0.05 can be assumed 

REJECT the hypothesis, because p-value (0.036) < the alpha value assumed which is 0.05

66.

Naddik [55]

Answer: 530.66 units²

Step-by-step explanation:

$Area_{(circle)}=\pi r^2\qquad and\qquad r=\dfrac{diameter}{2}\\\\\\\implies Area_{(circle)}=\pi \bigg(\dfrac{diameter}{2}\bigg)^2\\\\\\\text{It is given that the diameter = 26:}\\A=\pi\bigg(\dfrac{26}{2}\bigg)^2\\\\\\.\quad =\pi \cdot 13^2\\\\\\.\quad =169\pi\\\\\\.\quad =\large\boxed{530.66}$

In what time will Rs. 5600 amount to Rs. 6720 at 8% per annum?

Leona [35]

Answer: 2 years

Step-by-step explanation:

If Interest= Principal x rate x time/100; then time is (100 × Interest)/(Principal × Rate)

From the question, old Principal is 5600, new principal =6720, the difference is the interest accrued.

Interest = 6720 - 5600 = Rs 1120

Rate = 8% = 8 ÷ 100 = 0.08

Time = x

Then, slot the values into the formula

Time= 100 x 1120 / 6720 x 8

= 112000/53760

=2.08

Time= 2years

I hope this helps

Scientists found the wreck of the titanic 3797 m below sea level. How many km below sea level is the wreck?

WINSTONCH [101]

We are given that the titanic is found 3,797 m below sea level. This is simply equivalent to 3.797 km or 3.8 km when rounded off to one decimal.

We should take note that the letter k in km means kilo and a kilo is equivalent to 1000. So this means that for 1 km there is exactly 1000 m. So to convert, simply multiply a value with unit m with this conversion factor. Conversion factor = 1 km / 1000 m

Depth of titanic = 3,797 m (1 km / 1000 m)

Depth of titanic = 3.797 km = 3.8 km
