Suppose that scores on the mathematics part of a test for eighth-grade students follow a Normal distribution with standard devia
riadik2000 [5.3K]

Answer:

We need an SRS of scores of at least 153.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.9}{2} = 0.05

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.05 = 0.95, so z = 1.645

Now, find M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

How large an SRS of scores must you choose?

This is at least n, in which n is found when M = 20, \sigma = 150. So

M = z*\frac{\sigma}{\sqrt{n}}

20 = 1.645*\frac{150}{\sqrt{n}}

20\sqrt{n} = 1.645*150

\sqrt{n} = \frac{1.645*150}{20}

\sqrt{n} = 12.3375

(\sqrt{n})^{2} = (12.3375)^{2}

n = 152.2

Rounding to the next whole number, 153

We need an SRS of scores of at least 153.

Explain the purposes of inductive and deductive reasoning in mathematics. Be sure to define both inductive reasoning and deducti
uysha [10]
When it comes to deductive reasoning, it is used to reach a logical solution. You start out with the general statement, or hypothesis, and examine all the possibilities so you can reach the final conclusion. 
Inductive reasoning is completely opposite - you focus on specific observations, and then make broad generalizations.

1.60. वात्सल्य के अन्तर्गत शिशु स्वरूप के सौंदर्य की अपनी महत्वपूर्ण भूमिका होती है । आपने भी जीवन में
Rus_ich [418]

Answer:

hope it helps

please mark me brainliest

Step-by-step explanation:

वात्सल्य रस का स्थायी भाव है। माता-पिता का अपने पुत्रादि पर जो नैसर्गिक स्नेह होता है, उसे ‘वात्सल्य’ कहते हैं। मैकडुगल आदि मनस्तत्त्वविदों ने वात्सल्य को प्रधान, मौलिक भावों में परिगणित किया है, व्यावहारिक अनुभव भी यह बताता है कि अपत्य-स्नेह दाम्पत्य रस से थोड़ी ही कम प्रभविष्णुतावाला मनोभाव है।

संस्कृत के प्राचीन आचार्यों ने देवादिविषयक रति को केवल ‘भाव’ ठहराया है तथा वात्सल्य को इसी प्रकार की ‘रति’ माना है, जो स्थायी भाव के तुल्य, उनकी दृष्टि में चवर्णीय नहीं है[1]।

सोमेश्वर भक्ति एवं वात्सल्य को ‘रति’ के ही विशेष रूप मानते हैं - ‘स्नेहो भक्तिर्वात्सल्यमिति रतेरेव विशेष:’, लेकिन अपत्य-स्नेह की उत्कटता, आस्वादनीयता, पुरुषार्थोपयोगिता इत्यादि गुणों पर विचार करने से प्रतीत होता है कि वात्सल्य एक स्वतंत्र प्रधान भाव है, जो स्थायी ही समझा जाना चाहिए।

भोज इत्यादि कतिपय आचार्यों ने इसकी सत्ता का प्राधान्य स्वीकार किया है।

विश्वनाथ ने प्रस्फुट चमत्कार के कारण वत्सल रस का स्वतंत्र अस्तित्व निरूपित कर ‘वत्सलता-स्नेह’ [2] को इसका स्थायी भाव स्पष्ट रूप से माना है - ‘स्थायी वत्सलता-स्नेह: पुत्राथालम्बनं मतम्’।[3]

हर्ष, गर्व, आवेग, अनिष्ट की आशंका इत्यादि वात्सल्य के व्यभिचारी भाव हैं।
