Svetlanka [38]

Let X be the iq score of adults. X is normally distributed with mean of 100 and standard deviation of 20.

If all iq scores are converted to z -scores then we will get z scores. And the z score is standard normal variable with mean=0 and standard deviation =1

Hence the mean and standard deviation of of all z scores will be 0 and 1 respectively.

djyliett [7]

Answer:

More than 50% would germinate

Step-by-step explanation:

Given that in the production of a plant, a treatment is being evaluated to germinate seed. From a total of 60 seed it was observed that 37 of them germinated

Let us check whether more than 50% will germinate using hypothesis test

H_0: p = 0.50\\H_a: p>0.50\\

(right tailed test)

Sample proportion p =\frac{37}{60} =0.617\\q = 0.383\\Std error = \sqrt{\frac{pq}{n} } =0.0628

p difference = 0.117

Test statistic Z = p difference/std error = 1.864

p value =0.0312

Since p value <0.05 our significance level of 5% we reject null hypothesis

It is  possible to claim that most of the seed will germinate (i.e. more than 50%)

A=(1/2)(r^2)(sin[360/n])(n)
A=(1/2)(8^2)(sin[360/15])(15)
A=(1/2)(64)(sin[24°])(15)
A=(1/2)(64)(0.40673664)(15)
A= 195.2335872
