Female athletes at the University of Colorado, Boulder, have a long-term graduation rate of 67% (Source: Chronicle of Higher Edu

VLD [36.1K]

Answer:

Yes, we can assume that the percent of female athletes graduating from the University of Colorado is less than 67%.

Step-by-step explanation:

We need to find p-value first:

z statistic = (p⁻ - p0) / √[p0 x (1 - p0) / n]

p⁻ = X / n = 21 / 38 = 0.5526316

the alternate hypothesis states that p-value must be under the normal curve, i.e. the percent of female athletes graduating remains at 67%

H1: p < 0.67

z = (0.5526316 - 0.67) / √[0.67 x (1 - 0.67) / 38] = -0.1173684 / 0.076278575

z = -1.538681

using a p-value calculator for z = -1.538681, confidence level of 5%

p-value = .062024, not significant

Since p-value is not significant, we must reject the alternate hypothesis and retain the null hypothesis.

marusya05 [52]

Answer:

24 rounds

Step-by-step explanation:

This question has to do with a factor of numbers which we refer to as:

Lowest common multiple.

Lowest common multiple can be defined as the Lowest multiple that is common to the multiple of two numbers.

We are told in the question that:

Lloyd is making goblins and elves on a video game. It takes 6 rounds to make a goblin and 8 rounds to make an elf.

We find the multiples of 6 and 8

6 = 1, 6, 12, 18, 24, 48, 54, 60, 66, 72 e.tc.

8 = 1, 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, e.t.c

The Lowest Common Multiple: This is the least or lowest multiple that is common to both 6 and 8

= 24.

Therefore, it will take 24 rounds for Lloyd to complete another goblin and elf at the same time

A furniture store received an order for 8,367 tables they can fit 7 tables in the lower shipping box how many shipping boxes whe

-BARSIC- [3]

1195 boxes are needed to ship all the tables

<em><u>Solution:</u></em>

Given that, furniture store received an order for 8,367 tables

They can fit 7 tables in the lower shipping box

To find: Number of shipping boxes needed to ship all the tables

From given,

Total number of tables = 8367

Number of tables fit in one shipping box = 7

Thus, we can find the number of shipping boxes needed to ship all the tables by dividing total number of tables by number of tables fit in one shipping box

$\text{Number of shipping boxes needed } = \frac{\text{Total number of tables}}{\text{Number of table fit in one box}}$

Substituting the values we get,

$\text{Number of shipping boxes needed } = \frac{8367}{7}=1195.28 \approx 1195$

Thus 1195 boxes are needed to ship all the tables
