Answers

Simon will pay £18 in VAT for using 3000 units of electricity in one year.

The VAT rate for gas and electric is 5%.

Therefore, Simon will pay VAT on his electricity usage.

Let's calculate Simon's annual electricitycost without VAT:

Cost per unit of electricity = 12p

= £0.12

Number of units used in one year = 3000

Electricitycost without VAT = Cost per unit × Number of units

= £0.12 × 3000

= £360

Now, let's calculate the VAT amount:

VAT rate = 5% = 0.05

VAT amount = Electricitycost without VAT × VAT rate

= £360 × 0.05

= £18

Therefore, Simon will pay £18 in VAT for using 3000 units of electricity in one year.

A survey by the American Veterinary Medical Association found that out of 120 families surveyed, 18 owned a bird. Fifteen years ago, a similar study found that only 5 families out of 100 surveyed had a bird. Are the validity conditions for a two-sample z-test/interval adequately met

Answers

Answer:

Step-by-step explanation:

The assumptions include:

The samples from each population must be independent of one another: this was adequately met.

The populations from which the samples are taken must be normally distributed: this was not talked about

The population standard deviations must be known: not known

or the sample sizes must be large (i.e. n1≥30 and n2≥30: true

The validity conditions for a two-sample z-test/interval were not all adequately met
