pishuonlain [190]

Answer:

(a) Continuous,

(b) Discrete,

(c) Continuous.

Step-by-step explanation:

We are asked to classify each variable as discrete or continuous.

(a) The time it takes to drive to University.

We know that continuous data can take any values within a range, while discrete data can take only certain values.

Height, weight, time are typical examples of continuous data.

Since it can take some minutes or hours to reach university, therefore, the given variable is continuous.

(b) The number of credit cards a person has.

The number of credit cards a person can take lie in the group of positive integers. Since a person can take finite number of credit cards, therefore, the given variable is discrete.

(c) The weight of pumpkins.

We know that the weight of all pumpkins cannot be similar. The weight of pumpkins can be between some kg to some pounds, therefore, the given variable is continuous.

There are 527 pencils,646 erasers and 748 sharpeners. These are to be put in separate packets containing the same number of item
sp2606 [1]

Answer:

  • 31 pencils
  • 38 erasers
  • 44 sharpeners

Step-by-step explanation:

The number of packets is the greatest common divisor of the given numbers of pencils, erasers, and sharpeners.

It can be helpful to look at the differences between these numbers:

  748 -646 = 102

  646 -527 = 119

The difference of these differences is 17, suggesting that will be the number of packets possible.

  527 = 17 × 31

  646 = 17 × 38

  748 = 17 × 44

The numbers 31, 38, and 44 are relatively prime (31 is actually prime), so there can be no greater number of packets than 17.

There will be 31 pencils, 38 erasers, and 44 sharpeners in each of the 17 packets.

_____

We may have worked the wrong problem. The way it is worded, the <em>maximum</em> number of items in each packet will be 527 pencils, 646 erasers, and 748 sharpeners in one (1) packet. The <em>minimum</em> number of items in each packet will be the number that corresponds to the maximum number of packets. Since 17 is the maximum number of packets, each packet's contents are as described above.

17 is the only common factor of the given numbers, so will be the number of groups (plural) into which the items can be arranged.

Consider the following hypothesis test. H0: μ = 15 Ha: μ ≠ 15 A sample of 50 provided a sample mean of 14.11. The population sta
bearhunter [10]

Answer: -2.10

Step-by-step explanation:

Given : H_0:\mu=15

H_a:\mu\neq15

Sample size : n= 50, since the sample size is greater than 30 , so we apply z-test.

Sample mean : \overline{x}=14.11

Standard deviation : \sigma= 3

The test statistic for population mean :-

z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}

i.e. z=\dfrac{14.11-15}{\dfrac{3}{\sqrt{50}}}=-2.09775011752\approx-2.10

Hence, the value of the test statistic = -2.10
