Answer:

A) A sign on a bridge reads, "Maximum height of vehicles is 14 feet."

Step-by-step explanation:

If h represents the maximum height of vehicle in feet,

Maximum height of vehicles is 14 feet,

i.e. h is less than or equal to 14,

⇒ h ≤ 14

Maximum height of vehicles is equal to 14 feet.

i.e. h = 14

Maximum height of vehicles is greater than 14 feet,

i.e. h is greater than 14,

⇒ h > 14

Maximum height of vehicles is greater than or equal to 14 feet.

i.e. h is greater than or equal to 14,

⇒ h ≥ 14

Hence, OPTION A is correct.

Suppose a long jumper claims that her jump distance is less than 16 feet, on average. Several of her teammates do not believe he
Greeley [361]

Answer:

Claim : Jump distance is less than 16 feet.

A ) H_0:\mu \geq16\\H_a: \mu

n = 19

Since n <30 we will use t test

The mean distance of the sample jumps is 13.2 feet. i.e. x = 13.2 feet

The standard deviation of her jump distance is 1.5 ft i.e. s = 1.5

Formula : t =\frac{x-\mu}{\frac{s}{\sqrt{n}}}

Substitute the values:

B) t =\frac{13.2-16}{\frac{1.5}{\sqrt{19}}}

t =−8.136

degree of freedom df = n-1 = 19-1 = 18

\alpha = 0.1

t_{(\frac{\alpha}{2},df)}=1.73

t critical > t statistics

So, we accept the null hypothesis

C) So, the claim is wrong that ump distance is less than 16 feet.

Hence long jump distance must be greater than or equal to 16

A drama class has a total of 31 Students. the number of females is 17 less than the number of males. How many males and how many
Anika [276]

Answer:

24 males

7 females

Step-by-step explanation:

<u>Step 1: Write the data</u>

Total number of students: 31

Number of males: x

Number of females: x - 17

<u>Step 2: Form an equation</u>

males + females = total students

x + x - 17 = 31

2x = 48

x = 24

There were 24 males

<u>Step 3: Find the number of females</u>

Number of females = x - 17

Number of females = 24 - 17

Number of females = 7

Therefore, there were 24 males and 7 females in the class.
