Please explain step by step for 0.67÷0.3=?
pentagon [3]
Multiply each of the numbers by a ten to a power that they both become whole numbers.

0.67 * 10^2 = 67
0.3 * 10^2 = 30

Divide as usual.

67 / 30 = 2 \frac{1}{3}

So, the answer is 2 1/3.

Perform a one-proportion z-test for a population proportion. Be sure to state the hypotheses and the P-Value. State your conclus
emmainna [20.7K]

Answer:

There is not enough statistical evidence in the sample taken by the veterinarian to support his skepticism

Step-by-step explanation:

To solve this problem, we run a hypothesis test about the population proportion.

Proportion in the null hypothesis \pi_0 = 0.37

Sample size n = 150

Sample proportion p = 54/150 = 0.36

Significance level \alpha = 0.05

H_0: \pi_0 = 0.36\\H_a: \pi_0

Test statistic = \frac{(p - \pi_0)\sqrt{n}}{\sqrt{\pi_0(1-\pi_0)}}

Left critical Z value (for 0.01) Z_{\alpha/2}= -1.64485

Calculated statistic = = \frac{(0.36 - 0.37)\sqrt{150}}{\sqrt{0.37(0.63)}} = -0.254

p-value = 0.6003

Since, test statistic is greater than critical Z, the null hypothesis cannot be rejected. There is not enough statistical evidence to state that the true proportion of pet owners who talk on the phone with their pets is less than 37%. The p - value is 0.79860.

A dice is thrown and a coin is tossed what is the probability of rolling a 3 and getting heads
Maksim231197 [3]
A die in the shape of a cube has 6 faces going from 1 - 6 inclusive, unless you have some sort of die that is not a standard. A coin has to faces. You would be surprised the number of times I've had to clarify this.

The probability of getting heads is 1/2 [the other half goes to getting tails].

The probability of throwing a die and getting a 3 is 1/6.

The probability of getting both at the same time is 1/6 * 1/2 = 1/12.

1/12 <<<<< answer.
