Work out the value of his car at the start of 2017.

Answers

The value of Mike's car at the start of 2017 is £4116.

What is percentage ?

Percentage is a ratio in the form of fraction of 100.

Percentage is defined by the "%" symbol.

What is the required value of the car ?

At the start of the year 2014, Mike's car was worth £12000.

The value of the car decreased by 30% every year.

So, The value of the car at the start of 2015 = £12000×(1-(30)/(100))

                                                                         = £ 12000×(7)/(10)

                                                                         = £ 8400

Again, The value of the car at the start of 2016 = £8400×(1-(30)/(100))

                                                                              = £8400×(7)/(10)

                                                                              = £5880

∴ The value of the car at the start of 2017 = £5880×(1-(30)/(100))

                                                                     = £5880×(7)/(10)

                                                                     = £4116

g Which of the following is true about a p-value? Group of answer choices It measures the probability that the null hypothesis is true. It measures the probability of observing your test statistic, assuming the null hypothesis is true. It measures the probability of observing your test statistic, assuming the alternative hypothesis is true. It measures the probability that the alternative hypothesis is true.

Answers

Answer:

It measures the probability of observing your test statistic, assuming the null hypothesis is true.

Step-by-step explanation:

The p-value, also known as the probability value measures the probability of observing your test statistic, assuming the null hypothesis is true.

A low p-value means a higher chance of the null hypothesis to be true.

It lies between 0 and 1. A small p-value indicates fewer chances of the null hypothesis to be true.

Question Two :A discrete random variable X has negative binomial distribution,
with 6 successes required each with probability of success 0.4
Determine the value of ...
a) ...E(X).
b) ... Var( X)
c) ... P ( X = 12).

Answers

Using the negative binomial distribution, it is found that:

a) E(X) = 15

b) Var(X) = 6.67

c) P(X = 12) = 0.0883

Negative binomial distribution:

It is the number of trials until q successes of a binomial variable, with p probability of success.

The expected value is:

E(X) = (q)/(p)

The variance is:

Var(X) = (pq)/((1 - p)^2)

The probability mass function is:

P(X = x) = C_(x+q-1,q-1)(1 - p)^xp^q

C_(n,x) = (n!)/(x!(n-x)!)

In this problem, the parameters are: q = 6, p = 0.4.

Item a:

E(X) = (6)/(0.4) = 15

Item b:

Var(X) = (6(0.4))/((1 - 0.4)^2) = 6.67

Item c:

P(X = 12) = C_(17,5)(0.6)^12(0.4)^6 = 0.0883
