According to the Pew Research Center, the proportion of the American population who use only a cellular telephone (no landline)

is 37%. Jason claims that the proportion of young American adults who do not have a landline is greater than 37%. He conducts a survey with a sample of randomly selected young American adults and finds that 38% do not have landlines. If we set up our null and alternative hypotheses as follows: H 0 : p = 0.37 H a : p > 0.37 and find that: "p-value"=0.418. Does this provide enough evidence to support Jason’s claim? Use an α=0.05 level of significance.
a. Since the p-value < α, do not reject the null hypothesis.
b. Since the p-value > α, do not reject the null hypothesis.
c. Since the p-value < α, reject the null hypothesis.
d. Since the p-value > α, reject the null hypothesis.

Answer:

Answer =b. Since the p-value > α, do not reject the null hypothesis.

Step-by-step explanation:

The null hypothesis is to be rejected if the p- value is less than the given significant level. In this case, the p-value is 0.418 and level of significance α=0.05; the p-value is greater than level of significance therefore we do not reject the null hypothesis.

Answer:

<em>1. We can't see any boat on the river at this scale.</em>

<em>2. 0.025 inches. We won't be able to see it</em>

<em></em>

Step-by-step explanation:

<em>the beginning of the question states that; according to this map, the driving distance is 3 miles, we're most interested in the graphics at the bottom left, which indicates that 1 inches on the map corresponds to 2,000 ft in real life.</em>

<em />

If 1 inches = 2000 ft,

x inches = 50 ft

we cross multiply to give

2000x ft = 50 ft-inches

x = 50/2000 =<em> 0.025 inches</em>

If sin 20 degree=a and cos20 degree=b then which of the following represents the correct value of sin 70 degree in terms of a an
Scorpion4ik [409]

ANSWER

3) b

EXPLANATION

Given that:

\sin(20 \degree)  = a

and

\cos(20 \degree)  = b

Recall that the sine and cosine functions are equal for complementary angles.

This implies that,

\sin(70 \degree)  =  \cos(20 \degree)

\sin(70 \degree) = b

In a random sample of 90 students in first grade, the mean hours of sleep per night was 9.2 with a standard deviation of 0.37 in
ss7ja [257]

Answer:

Option C is right

Step-by-step explanation:

Given are two samples

I group has sample size 90, mean = 9.2 and std dev =0,.37

II group has sample size 70, mean = 7.3 and std dev = 0.58

we find that mean difference i.e. difference between mean hours of sleep between two groups

= 9.2-7.3 = 1.9

Std error for difference = 0.0620

Since sample size is sufficiently large we can use Z critical for 99%

i.e. 2.58

Margin of error =±2.58(0.062)

=0.16

Hence confidence interval 99% for difference in hours of sleep

= (1.9-0.16,1.9+0.16)

=(1.74, 2.06)
